5Works perfectly
By Matt
Please disregard the other reviews, they are for the outdated models. When you order this you will get the ihas 124b, not A or Y. I ordered one for myself my dad and a friend of mine bought one as well. They all work perfectly. Note, if your looking for smart erase, this drive doesn't have it. Also note, smart erase destroys your disc, it does not make it so you can rewrite data to the disc. If you werep looking at this but was turned away by the reviews, buy it.

5This is the B revision. Works perfectly for XDG3 XBox 360 backups!
By JMH
This drive was a B revision manufactured in August 2011. After installing the Burner Max firmware this drive handled burning of XDG3 backup discs flawlessly. Highly recommended!

2Watch out for the poor QC issue
By Y. Wang
The spec of this phone looks good among all of the budget phone, and that is the reason I purchased it last Saturday. Unfortunately, my phone arrived with a faulted proximity sensor that every time when I make a phone call, the screen will directly go black until the end of the call. After did some searches on the internet, I figured out my situation was not a single case. There are some discussions about the proximity sensor issue across nearly entire Huawei's products line, including the G330, G510 and other phones. So, if you are interested on this phone, be careful for their poor QC, and carefully check your phone when it arrive.
In addition of the QC issue, Huawei tried to build their own UI instead of the standard Android interface. Again, unfortunately, their-own interface is not that user friendly, and does not give many plus to this phone...
The only reason that I will give this phone two stars, instead of just one, is the camera on the back. Its hard to find a phone with this price range come with the LED flash. Although the camera is only 5M pixels, the additional flash really helps to increase the usage of this phone, makes it easy to use indoor.

4Older HP Dv7 - Wifi works great - Bluetooth No Go BUT...
By digitalPimple
The card works great and my speeds over AC are a nice improvement. I am still bottle-necked as I'm using an older HP-DV7 1000 series laptop with this card.

For those that may not know; if you receive an error at start-up after install, this means your laptops manufacture has blocked the card from working (Only approved cards). You will need to re-flash your laptops bios/firmware with a modified version that remove this 'blocking' function. (white listed)

You can find a few sites out there that specialize in listing modified bios/firmwares based on your laptops model and bios/firmware version removing the 'white listing' completely. Take your time with this if you're new.

---------------

Intel now offers the drivers for this card. If you want to use the Bluetooth function be sure to get the Bluetooth Intel software package FIRST before installing the Intel Wireless Drivers.

The Bluetooth works only over G wireless so be prepared for setup issues and some playing. Read Intel instructions on this. This may not just be a plug and play feature for your situation.

Good luck!

5Great product from Intel
By J. Bennett
I purchased this card in combination with the new ASUS RT-AC66U where I installed DD-WRT. I installed this card on my Lenovo V570 after removing the BIOS blacklist. The Lenovo V570 has two antennas so that worked well with this card. I downloaded the drivers from Intel and installed them on a Windows 7 x64. It works very well, so far I have not experienced any disconnects as other users have, maybe because I used the latest Intel driver. I have not tested bluetooth.

I have configured my router for 80Mhz of bandwidth at 5Ghz 802.11ac and 40Mhz for 2.4Ghz. I have also checked the settings for the Intel AC 7260 and changed the following:

- 802.11n Channel Width for 2.4Ghz: Auto
- 802.11n Channel Width for 5.2Ghz: Auto
- Preferred Band: 3. Prefer 5.2Ghz band

I also checked multiple channels for the 5Ghz interface. Some channels were pretty bad with connection speeds of 70mbit/sec.

I have my router upstairs and use the laptop downstairs. The connection speed at 5GHz shows in DD-WRT and Windows at 585 mbit/sec. My old 802.11n card was connecting at 144 mbit/sec. After testing some file transfers, the effective bandwidth was around 15MB/sec, which is effectively around 120mbit/sec, 10 times the 1MB/sec that I was getting with the 802.11n. In theory I should be seeing transfers of 60-70 MB/sec but I am happy with my 10x improvement. Now if you are testing this card by transferring some files, your storage needs to be able to handle these transfer speeds. I have a 10TB storage array connected to my server via 4Gigabit Fibrechannel that can do more than 300MB/sec (limited by the 1gbit/sec network connection of the router to 120MB/sec) and I use an Intel last generation flash SLC drive on my laptop that will easily do 100MB/sec, so my backend storage can support true 1 gigabit/sec.

One last thing, be aware that the seller SPICY BOMB is selling fake cards. These cards are Atheros AR9462/AR5BWB222 with a photocopied sticker from an Intel card. These are not even AC wireless cards. If you purchased this card from SPICY BOMB, please look at the sticker and see if you have WFM: 0C8BFD2C745A and BDM: 0C8BFD2C745E. If you do, you have the fake card. You can also identify the fake because the antenna connectors are marked CH0 and CH1 instead of 1 and 2 like the Intel.

5Great upgrade for my Dell XPS 17!
By John Platt
My Dell XPS 17 (Model L1702X) was having problems with it's built-in Intel 6230N wireless card, so I finally decided to replace it. After studying on new cards i wanted to get a card that could use the full potential of my new Router (NETGEAR Wireless Router - AC1750 Dual Band Gigabit (R6300) - Manufacturer Refurbished. Mine was purchased from Mobile Computing Solutions and shows up as the Intel Dual Band Wireless-AC 7260. It connects at 866.7 Mbps to my netgear R6300 version 1 router using the Wireless AC standard which is amazingly fast, it's almost like connecting with a cable.

Installation:
I downloaded the latest windows 7 drivers previously. You need to first download the Bluetooth drivers which for windows 7 64bit is BT_3.1.1311_s64. Then I had to find the windows drivers. I used the drivers only which is Wireless_16.6.0_Ds64. There is also a newer Wireless_16.7.0_Ds64 that is out as well.

I looked up dissassembly instructions online for my Dell XPS 17 Laptop (L1702X). I took apart my case and removed my Wireless card, which had two wires connected but three available (one was wrapped and not used). It replaced an Intel 6230N. I then put in the new card and used the previous screw to screw it in. The antenna wires were popped back on the same sides. I then put my laptop back together which was hard since I had to remove the keyboard and several small screws from throughout the system.

I then booted the laptop and installed the bluetooth drivers and network drivers again. I then connected to my wireless network using the new card.

Troubleshooting: I was only connecting at 54Mbps at first and I was having connection issues. Here is how I fixed it...
For those with wireless-n and wireless-ac routers you may have to troubleshoot your windows settings if you have "upgraded" your card. In the control panel, go to the Device manager, go to network section, and double-click on the Intel Dual Band Wireless-AC 7260. Now clicked on Advance. Under Ad-hoc choose WMM Enabled, under HT mode choose VHT, under preferred band choose 5.2ghz, under transmit power choose 5 highest, and under wireless mode choose 6: 802.11 a/b/g. Press okay to save changes.

Inside your router go to the QOS section (in my netgear router it can be found in advanced>Setup>QOS Setup). Make sure WMM is enabled. Save changes.

Another thought is to use a program like DNS Bench to find the best DNS server for you. I added my provider's DNS to the generated list and it turned out that Charter's DNS (one of the two provided) was the fastest and a level 3 dns server was second fastest for me. I added both as static dns server's to my router.

Final Thoughts:
I love this wireless card. You'll have to ignore the Windows 7 bug that claims you are connecting to a Wireless N network and the driver bug that states you only connect to a/b/g networks. The one device bug right now is that your router needs WMM enabled. This does not make sense since my wireless AC usb adapters such as the Edimax AC adapter, did not have this problem. Overall the Intel 7260 connects faster than the Edimax EW-7811UTC AC600 Dual-Band USB Adapter, Mini Size Easy to Carry, Supports Both 11AC ( 5GHz Band ) and 11n ( 2.4GHz Band ) Wi-Fi Connectivity, Upgrades your PC / Laptop for Exceeding Streaming and Faster Download. It actually is twice as fast since its 866.7 Mbps compared to 430Mbps , not to mention it fits inside my laptop so I can't break it. Overall if you don't mind opening your laptop this is a great deal for Wireless AC router owners!

4Good, but could use some improvements to build quality.
By Beau L.
This is a good dual card reader. I have a version that only reads CF cards from Lexar for firewire 800. That's actually a better built device, but you don't always have access to firewire, and can't read SD cards. This card reader works well, but the "pop-up" feature of the reader seems a little bit cheesy and doesn't always pop up easily, but otherwise had been working good so far. The pop-up feature does however allow you to transport it more compactly in your laptop case, etc.

5Check the model number on the actual reader
By jordan
Hello fellow Amazonians. I received this item and am very pleased with the build quality, size and look. The box has a label placed over the original printed box label with the current model number LRW307URBNA, but the reader has a label on it, which has the part number LRW300U which is old and I confirmed that with the mfg. Please contact Amazon if you have the same issue if you care. This is a careless mistake on Amazon's part or the mfg., but the mfg. claims Amazon must have miss packaged it somehow. I will readjust as necessary. Amazon did a refund because item is no longer available through them. Figures. I will probably purchase somewhere else like BHphoto&video for a better chance of the actual model.

Update_2012-07-14: I purchased one from B&H Photo & Video. Same thing happened. Box says UDMA 7 support (sticker) and barcode on bottom says LRW307URBNA. Inside, the unit has a model # of LRW300U. I was very curious how this happened again, so I called Lexar tech support instead of email. Well I immediately was on the line with someone who knew what they were talking about. The unit needs a firmware update. The only change from the LRW300 to LRW307 is firmware, so even if you have a LRW300, you can update it. I now raise my rating. Thanks

Update 2013-11-22: Please disregard previous reviews. It was the manufacturers fault to not update their packaging and just place stickers on the box, but everything is fine. Love the reader.

1bought two this year, both failed
By Pilgrim
I'm not product basher, but I get angry when a critical piece of equipment fails TWICE. I purchased the Lexar Dual Slot USB 3 LRW307URBNA in January 2013 and it stopped working completely in July. I didn't have time to squabble so I purchased another on July 29, 2013. Today the second device stopped working (1 of the 2 slots). I do not recommend this product.

5Great Product for a Great Price
By Duane
1st off, the refurbished product doesnt come with the Smart Wizard disc, you dont need it, its all pre-loaded into the router.

Connect your PC to the router (hard wire) and type [...] on a browser, login ID is admin, password is password, from there you can configure the whole router to your hearts content.

when you first log in, it will check for any updates to the firmware, DO NOT UPGRADE TO 1.0.0.50, stay with 1.0.0.38 that's currently loaded on there, its far more stable and reliable, you can uncheck the "check for new version" box so this doesnt bother you again.

i made the mistake of upgrading to 1.0.0.50, my 5ghz band was incredibly unstable and died every 2-3 hours, also lost the ability to turn off the bright blue LED lit dome with the new firmware.

if you fell into this hole like i did. go to[...] and download the 1.0.0.38 firmware. it will ask you for the router serial number (of which the refurbished routers dont have one), to the right of the red download button is a link that says "continue without registering" click this and it will allow you to download the 1.0.0.38 firmware. go to your router admin screen (using the access method i mentioned above)\Maintenance\Router Upgrade, use this window to downgrade back to 1.0.0.38

Wireless N 600 speed is awesome, very noticable upgrade from my AT&T Wireless G router imbedded in my home gateway. the router is increadibly stable, no issues day-over-day, it just works, just what you would expect from a NetGear.

4Why pay full price?
By Luis
I just set up this router and am extremely happy about it. It is aesthetically pleasing as well as functional. NOTE: My ONLY complaint (and this is in part my fault) is that this router DOES NOT support the ReadyShare Cloud. When I was looking into ReadyShare on Netgear's website I misread that there is indeed a difference between ReadyShare and ReadyShare Cloud. ReadyShare allows you to connect an external hard drive to your wireless router and you can access that hard drive wirelessly while connected to the router its attached to...this is different than ReadyShare Cloud in which you can access the hard drive connected to the router ANYWHERE ON THE PLANET. Only the Netgear 3800 is compatible with the ReadyShareCloud feature. Now this doesn't detract from this product, it just wasn't very clear that the 3400 DOES NOT have the ReadyShareCloud feature.

Overall however, I really liked this product and at the refurbished price, it can't be beat.

5Very Easy Setup
By Dorothy Mantooth
I purchased this router basically for two reasons:

1. I need more bandwidth for all of my devices

2. It was a cost effective solution for the amount of bandwidth.

After struggling with an older Netgear N300 (which was not horrible, just limiting)...I decided to fork out the dough for a "new" router. I had seen this N600 at best buy (where it was $80+ I think) and asked the sales person about it. They mentioned that they had it for a while and it did the job while supporting 2 laptops, an Xbox, a PS3, iPhone, and tablet. I was just about sold on it because I need support for 2 smartphones, 1 laptop, a PS3, a Wii, and a tablet. I decided to check the price on Amazon just in case and Wah Lah! I am not sure why there are so many "refurbished" N600's available, but after one month in: no restarts, no bandwidth glitches or delays while the kids are streaming Netflix to the PS3, and no dropouts when in the upstairs area of my home.

Setup was very easy. While I was scratching my head at trying to setup the router from my iPad, as soon as I turned on the laptop (with Windows 7), the new router was immediately recognized. I was asked for a new security password and router ID and I was up-and-running. No software to install, no setup "wizard" that asked me the color of my underwear, no fuss. It just worked.

4Not so MINI, but a good surge product overall.
By R. Ocampo
I've been searching for a product that can extend the outlet on my bathroom for the electrical products that I use. I finally came across this Belkin mini surge protector and features:

- 3 AC power outlets
- 2 USB outlets ONLY for charging (not data transfer) at 5V / 500mA at each port
- Surge protection on all 5 outlets
- 918 Joules Energy Dissipation
- 125V / 15A / 1,875W Continuous Duty Electrical Rating
- 36,000A Maximum Spike Current
- Lifetime Warranty on product
- USD75,0000.00 connected equipment warranty
- 360 degree rotating plug lockable into 4 possible positions

Simple, elegant design in a smooth plastic casing of white and light grey colour. Once plugged, the green LED light will indicate if the power source is grounded.

The box comes with one USB to mini-USB cable to get you started in charging your USB devices as well.

DO NOT throw the prong cover that initially comes attached to the surge protector prong. As the manual states (for those who still care to read the User Manual these days), you can use this plastic prong cover to help further balance the device against any surface. You do this by inserting the plastic prong cover on the bottom of the surge device via a small notch. Also, the plastic cover is handy to use when traveling. Before dumping the surge protector along with your other devices, cover the prongs to prevent it from scratching other objects.

The prongs can be rotated 360 degrees loosely. However, there are 4 positions that enable you to lock it so it doesn't flail along clumsily in any direction. You do this by pressing into the rear a "release button". It's not a raised button, but a flat plastic portion that you have to press hard in order to release the lock. It's quite difficult (at least with the model I received) at first and feels like I'm going to break the plastic button. But I guess if this is normal then it can be construed as a safety measure so it doesn't easily rotate with a simple touch.

IMPROVEMENTS:

The term "mini" is subjective. It isn't really that compact as I would assume from seeing the photo. It is small, yes. However, as a surge protector that can take 3 AC and 2 USB outlets, I will give Belkin the benefit of naming it a mini device.

I would STRONGLY prefer the re-design of the spacing on the AC outlets by allowing larger plugs connected side-by-side. As it is right now, only normal AC plugs and not block-style plugs are allowed without loosing all three outlets. So my proposal is to delete the middle AC outlet and move it to the end-cap of the device (opposite to the 2 USB outlets). As of now, there is nothing there so rather than cramp the 3 AC plugs, then move the third at the end and thus allowing for block-style plugs to be used and still retaining the 3 AC functionality.

OVERALL:

I would not hesitate to recommend the purchase of this surge protection for compact spaces as well as travel purposes especially with the lifetime warranty and amount of protection is offers.

Take note of the selling price Amazon and the others are selling this at. It's ridiculous to see the selling price of this exact device can range anywhere from USD10 to USD30.

Lastly, BE AWARE of the SPECS so you know if the USB device you are plugging is capable of being charged.

4Nice wall mounted surge protection with a slight vampire load
By Chris Jaronsky
I was shopping for surge suppressors and came across this Belkin wall mounted unit. I like wall mounted units better because I hate having power strips laying on the floor. This unit has the added bonus of having two USB charging ports on it.

Pros,
- 2 USB charging ports for phones, IPODs, etc.
- wall mounted.
- $25,000 insurance protection.

Cons,
- The USB chargers always draw a small bit of electricity even when not being used. I plugged this surge protector into my Kill A Watt Electricity Usage Monitor and found it drew a small current.
- The $25,000 insurance policy has some small print. Every cable going into your protected device needs to be run through an approved Belkin device. So if you plug in a TV, the coax connector has to be plugged into a Belkin device. Protecting a PC? You need to be using wireless, or you need to have your network cable going through an approved Belkin device. Not a major problem, just make sure you are actually covered by the insurance policy BEFORE a disaster hits.
- The outlets in my house are the square, flat type that do not have a center screw hole to mount this unit. I had to change the outlet to a standard outlet which since I had everything on-hand, and am comfortable with electrical work, took me about 5 minutes.

My overall opinion of this item is that it does its job as advertised. If it fits your needs and the slight vampire power load do not bother you, then it will work out just fine for you.

2USB output too low
By DP
**This review relates to the 1 Amp, 3-outlet version and was posted prior to the introduction of the new products and eventually being combined.

To get directly to this items flaw... It cannot recharge/power more than one USB item at a time. So what's the point in having two USB outputs?
The 120V outlets work as advertised. The ability to rotate the prongs is a plus as it can be adjusted to most if not all outlets.
The USB power fails if more than one item at a time is plugged into the surge protector. Even if, say your phone is fully charged, if you go to connect another item to run or charge, the surge protector will not supply the power that both items demand. The items that are connected will act as if they have been disconnected from their power source, then once the surge protector accumulates enough power(not certain, but seem to act as if there are capacitors)to start supplying power once again the items connected to the USB ports start to operate briefly until the surge protector cannot supply enough power for the two items.
As stated before, it will supply ONE item with power, without a problem. But will not supply enough power for two, even if one item is fully charged.

** Thank you Jeff Backe, I've been putting off editing this post in response to all the people saying that '500mA is the standard' for quite some time. This 500mA WAS the standard well before I made this purchase. The newer standard for wall chargers, which I believe this falls under, has been out since around mid 2007. This new specification is UP TO 1800mA(1.8A) per port.
When I made my purchase there also weren't the nice pictures that show you the current rates. So there really wasn't any way for me to know this until I received it.
Another thing, this item is rated at 500mA(.5mA) per port but is not actually limited to 500mA at the port if you only plug in one item. In other words, the way this item is configured it will actually put out the full 1000mA(1A)through one port, hence the reason you can plug in a high current draw device using one port. But when you plug in that second item the 1000mA is now split in half or however much each device is trying to draw. It is only able to keep up with this high demand for a short while until its capacitors are drained and cuts off supplying power, then quickly recharges the capacitors and re-establishes the supply of power once again. This cycling can't be good for either device.

5Very solid, especially for the price
By Olaf Piesche
Clamps to the desk with two finger screws, which doesn't seem like it would be very stable, but once installed it's rock solid. No wobble, it doesn't feel or look cheap. Very solid, relatively easy to install; height adjustment is only possible for both monitors at a time, not individually, but that's no big drawback. Cable clamps along each arm, which feel a bit flimsy but work. Comes with a surprisingly good, big, rubber coated allen wrench to tighten the screw that holds the arms vertically. Quick adjustment of the monitors is not possible, so it's a set-it-and forget-it mount. If you need to adjust monitor height frequently (such as transitioning from sitting to standing), this one's not for you. It's no-frills, but very good build quality. I don't think I'd be able to find another monitor mount of this quality for this price.

5Way better than expected given the price
By William Pallies
This stand is extremely sturdy and adjustable. I've had it for over a year now and have not had any problems with it. When I first bought it, I was expecting something satisfactory at best, given the low price. Every other VESA mount I had seen was at least double to quadruple the price, so I figured I'd be cheap and get something that works barely. Instead, this stand exceeded my expectations in every category. It mounts easily, is solid, looks good, and lets me adjust the display's tilt and angle with ease.

5Excellent Product and Price!
By Ookpic
Picked up this stand over the holidays. It has excellent quality! I have 2 Samsung 23" monitors mounted on it with no problems. VESA screws that came in the kit worked excellent. Unit is very adjustable, tilt, pan, height, etc etc. It even looks great!. If you are looking to clean up the clutter that sits in and around your monitor bases then this fits the bill. Even comes with built in clips to manage your cords! I would highly recommend.

5Best Alarm clock I have ever owned.
By Kay
I have bought tons of alarm clocks for travel and home. This one if the best. Has a USB jack with an A/B switch. So if your proprietary phone manufacture has switched pin in the USB. Then just flip the switch and it will work. So now we can charge all of our phones and iPods and Garmin GPS etc.. Alarms are easy to turn on or change. Great nap feature that is adjustable. And has an alarm volume plus night light that is adjustable. Everything you want in an alarm clock and more. I have one for travel and one for home.

4Great features, but a couple things I'd change
By D. Sabo
I purchased two of these Timex alarm clocks for my wife and I.
First off, for the price, this clock is packed with features. My main reason for choosing this was the multi level display dimmer; some clocks are just too bright. This one offers different levels of brightness and is perfect for me at the lowest level. The USB charger is convenient since I alway keep my phone on my dresser at night. Having a battery backup is also a must. I don't really have much use for the 2nd alarm or nightlight, but it doesn't hurt to have them.
The only 2 flaws I see are 1) every time you set the alarm, it beeps a confirmation that it's set (rather loudly). This is irritating when your partner is already asleep, but there's no way around it that I've found. And 2) Except for the large snooze button, the rest of the buttons are close together and are hard to differentiate in the dark by feel alone. Some space between them or raised surfaces on the buttons would have been welcome.
Overall I'm happy with these clocks. I would've given them 5 stars if there was a way to silence the beep when you set the alarm.

5Four Reasons I Like this Clock
By amy alexander
First, I like that is is compact and light. It is very small as you can see from the photo compared to a mobile phone.
Second, I like that it has a night light feature with three levels of brightness.
Third, I like that it has a USB port for charging devices.
Fourth, I like that it has a red display. I have found that sometimes the clocks with blue displays are so bright that they can light up a corner of a room. The red does not light the room but is still readable

2Work for iPad but not USB devices
By Mark
The packaging for the Scosche USBC202M dual iPad charger states "Works with iPad ... Android Devices"
That is misleading.

Short version: if the technical info below means nothing to you, don't buy this charger to use with any device except the iPad:

===
This will apparently charge the iPad at the full 2.1 amp rate (I haven't tried it with two iPads but based on other reviews assume it will do that too).

However, I bought two of these - for my iPad AND two different cell phones (Samsung Galaxy Nexus, Android and HTC HD2, Windows Mobile) which can both be charged at around 1 amp but neither of which will charge at more than 0.5 amp using this charger - the same rate achieved from a computer USB slot.
Other car chargers work just fine, using this one actually causes my Samsung phone to have less battery after a few hours driving than when I started.
This is also not immediately apparent because the phones look like they are charging but when you watch the charge over a few hours, or (with the Samsung) check the charging status, it says "USB charging".

This is caused by a USB/iDevice design challenge; to protect computers, early USB spec stated that no USB device may draw more than 0.5 amp unless the computer agrees to it. Later USB specs allow the two USB data pins to be shorted to go up to 1.7 amps - this is what my phone needs. As I understand it, the iPad requires specific signals on the 2 data lines to use the full 2.1 amp charge rate, and if connected to a charger that has shorted data pins - i.e. one that works well for most phones, will not charge at the full rate, if it charges at all. All this regardless of the maximum charge current the charger can provide.

My workaround is to acquire a cable that shorts the data pins for just the outlet I want to use with the phone.

Otherwise, for anyone that has two iPads, this is a super device - the smallest dual port iPad (2x 2.1A) charger I have seen yet and I love the low profile (most vehicle chargers consume way too much space outside of the vehicle outlet).

It would have given 3 stars if it had not used misleading wording on the packaging, 4 stars if the packaging had pointed out the USB challenges, and 5 stars if it had a mechanical or electronic switch to make it compatible with other modern USB devices.

4Needs a 'charge only' cable for Google Nexus 7
By Brad
As many reviews before state, this charger is designed for Apple devices. It requires a charge only cable to comply with the USB standards required by many android devices, which includes the Google Nexus 7.

5Great and powerful charger but you need a "charge only cable" for USB Devices!
By Techguru
The charger is great and provides an AC charge to my Samsung Galaxy S3. This basically means that using the charger with a "charge only" USB cable will make your phone think that it is plugged into the wall. Apple products DO NOT have this issue with charging on USB chargers as the technology that developed with the Apple charging system was designed to circumvent that specific problem. Apple users are good to go with any of their native cables. If you have an Android device, you will need to purchase a "charge only" USB cable...I cannot emphasize that enough!

Normal USB cables carry both data and charge and the data "communicates" with the USB effectively limiting the amount of power that can be received from a USB charger.

I can run GPS/Bluetooth /music/video and everything in between all a once and my phone will still charge via AC as confirmed on my GS3's charging screen. Normally it would say "USB charge" if i used my phones normal USB cable.

Here is the selection of "charge only" USB cables from 3BR Powersports, LLC that I use: http://www.amazon.com/gp/aag/main?ie=UTF8&asin=&isAmazonFulfilled=&isCBA=&marketplaceID=ATVPDKIKX0DER&orderID=&seller=ATHXXHPG0APQN

5Great charger for Apple products.
By Lee T. Sang
When I purchase an item like this I just want it to work as advertised and be solidly built. This New Trent charger doesn't disappoint on either part.

The first thing you should know is that the two USB ports are not equal. The top one is the one with more amperage while the bottom one has probably the same amperage as a PC's USB port. The reason I say that is because when I try to charge my iPad mini with the bottom USB port I get the same "Not charging" message I would get when I plug it directly into my PC's USB 2.0 port. Charging my iPhone 4 with the bottom USB port works just fine. Charging my iPad mini and iPhone 4 at the same time also works just fine.

This is a great upgrade for the iPad mini and a good alternative to Apple's own 10W charger. With the iPad mini's included 5W charger it took 3 hours and 15 minutes to charge from 28% - 100%. With this New Trent charger (in the top USB port of course) it only took 1 hours and 53 minutes to charge from 29% - 100%. That's about a 58% difference and the extra 1.25 hours is very noticeable.

There are situations where the size of the charger can prevent another AC plug from being plugged in when plugged into your wall outlet or extension/surge protector. For example, my wall outlet will not let me plug in two of these New Trent chargers at the same time. However, any normal sized plug (a cable that just ends in the 2 prongs with no power brick) will fit fine. Some big power bricks that have the prongs near the edge should work. Even the tiny charger that the iPad mini came with will fit fine. The charger has about 6/8" extra above the prongs when folded out and 5/8" extra below.

I really like the solid feel of the charger. The fold out prongs seem sturdy and really helps when you stuff it into your bag so it won't snag on anything or poke anything. Having two USB ports is great since you don't need to wait to charge your other device.

5Charges anything with a USB cable. Has a 1 Amp Port and a 2.1 Amp Port
By Sharp1
This New Trent 10W 5V/2A Dual Port charger (IMP90C) will charge just about any device that has a USB cable. I have many mobile devices and tested this New Trent IMP90C charger on all of them. It charged the following: Galaxy Note 2, Galaxy S3, iPhone 4, iPhone 3G, original iPhone (2G), original iPad, Blackberry Curve 9900, and Motorola SD10-HD bluetooth headset.

There are two ports for charging. The bottom port is 2.1 Amp. The top port must be 1 Amp. Note: When I refer to the top and bottom ports, this is with the charger oriented with the printed wording on the case right-side up, so you can read them properly.

The charging amperage is not clearly marked on the device, nor on the box. I get different results charging different devices.

Testing Results:
Samsung Galaxy Note 2 - can charge on both ports.
Samsung Galaxy S3 - can charge on both ports.
iPhone 4 - can charge on both ports.
Blackberry Curve 9900 - only charges on bottom port.
iPad (1st Generation) - only charges on the top port.

So, depending on your device, you may be able to use either port, or just a single port for that device. Charging with the 2 amp port will be faster than charging with the 1 amp port. I was able to charge multiple devices at once, with no issues. Charging times seemed to be just as quick as OEM chargers.

The collapsible prongs are a plus. You can fold them in to save space when traveling.

Overall this an excellent wall charger. The only improvement I could recommend would be to label the ports so their power output could be more apparent.

5Corsair Vengeance Blu 8 GB PC3-12800 1600mHz DDR3 240-Pin SDRAM Dual Channel Memory Kit
By W. Rehs
Purchased this kit to compliment a new build using a Gigabyte GA-890FXA-UD5 m/b, AMD Phenom II X6 1090T Black Edition CPU. Common to this and many other m/b's bios, the ram is initially recognized in bios as 1333MHz rather than this rams rated 1600MHz. Going into BIOS, 2 clicks of the mouse rectified that. For those only wanting or just starting out with 8GB of ram this kit is ideal. Two 4gb sticks using only 2 memory slots is more efficient than spreading the 8gb's over the four slots. My most immediate concern was compatibility with my M/B for it was not one listed as being tested for compatibility. I'm happy to report it is fully compatible with no issues. It thouroughly passed memtest, and my system has been running fast and stable since the day my build was born, about 2weeks now. O/S boot up is fast, opening applications is fast and multitasking is not a problem, but then I am running a 6 core CPU as well. I rather like the blue colored heatsinks, matches my board quite nicely but that's only cosmetically important, what counts is my PC's processing speed and stabilty and that earns this ram 5 stars, I couldn't be more pleased. I don't ever see the need to add another kit to make it 16gb but if that day should arise I would not hesitate to make this purchase once again. I highly recommend it. Fast, stable, fair price,the best warranty, no need to say more. Other than go ahead, buy it.

Update: 8/17/2011 I've added another one of these kits to my system to max out my board at 16gb. As expected, the additional ram did not notably increase my system performance. My reasoning behind adding the extra ram was because I could and I got a gold box deal on it. That being said, my initial review still stands in every aspect. Corsair ram rocks.

5Good Value Computer Upgrade
By Shooter12point7
I just got this kit today to replace a 2GB single-channel module, and I am very pleased. Boot-up of Windows 7 home Premium 64-bit is much faster on my machine now. The two 4GB modules were easy to remove from the box, and the plastic cases simply snapped open. No box cutter required. I was initially concerned that the new modules wouldn't fit under the power cable for my Micro-ATX motherboard because of the added height of the aluminum heat-dispersing shields. However, they will apparently fit anywhere a normal DDR3 desktop module will fit. Just as a test after booting up, I began rendering a quick 720p video, creating a home movie DVD, playing music, playing a DVD, playing two separate 720p videos, playing a random Youtube video, and browsing pictures on my hard drive all simultaneously. I was limited only when after a few minutes my Athlon II X4 2.9GHz Quad-core reached 100% load and 125 degrees F, causing the fan to run loudly. I decided to close some things at that point. Memory usage in Task Manager never got above 50% though, so I can't imagine ever needing more than 8GB of RAM for daily home use. Most programs have a barely noticeable load time now. Smaller programs that used to require a few seconds of load time now run instantly, and all programs run smoother and faster than before. If you have the money, your system supports 8GB of DDR3 RAM, and you want to improve your computer's performance, you can't go wrong buying this RAM kit.

5Super-fast, great range, lots of features
By S. Lionel
Pros:
+ Fastest dual-band router I have used by far
+ Lots of configuration options in admin panel
+ DLNA server, FTP server, USB printer server and USB storage server
Cons:
- Physically large
- Admin user interface can be confusing

For the last two-plus years I have been using the Netgear WNDR3700V1 dual-band router. At the time I bought it, it was considered one of the fastest dual-band routers available, and it had lots of features. It does work very well, but Netgear has revised it twice and the subsequent V2 and V3 releases have diminished functionality and performance. While I have used many brands of routers in the past, TP-Link was new to me so I was curious to see how the TL-WDR4300 compared.

The router itself is a large box. It's attractive and has a nice design, but it is much wider than competing routers. It is also very lightweight. Perhaps the width is so that the three dual-band antennae can be physically separated more - I don't know. There are keyhole slots on the bottom in case you want to wall-mount it, but as with most all routers, the wiring all goes to the back where the antennae are, so this might be awkward if your wiring comes from below.

TP-Link provides a setup "wizard" on a mini-CD (you can also download it from their web site), but I just connected to it directly and configured it through the admin panel. I was delighted to see that the wireless networks came up pre-configured with WPA security and an 8-digit password - many routers are simply "open" when first configured. This encourages users to maintain security. You can set the wireless to WEP or even open if you want, but that's generally ill-advised.

Unlike a certain other brand of router I have tried two examples of (cough - D-Link - cough), the TP-Link had no trouble negotiating with the Ethernet feed of my FiOS optical network box (the equivalent of a cable modem). Some of the configuration features it had that I liked were:

- Dynamic DNS support (though the selection of providers was limited)
- Separate and easy to understand configuration of 2.4 and 5GHz bands
- Ability to reserve IP addresses to specific devices

Some of the things I didn't like:
- Only a single display of DHCP clients connected, rather than separating wired from wireless
- IP reservation page did not let you select from known connections - you have to type the MAC address
- No "guest mode" - this is a feature the Netgear WNDR3700 has that adds a second network which can be configured to give Internet access only and not access to your local network. This is great for houseguests and the like [Edit - TP-Link added Guest Mode in a later firmware update]

The admin user interface is straightforward, though it uses submenus and some of the pages seemed to duplicate others. For example, there were two different pages where one could enter DNS server addresses, and changes to one did not carry over to the other. While each page had pretty good instructions right in the dialog, some of the options were a bit confusing as to how to set them. But what really got me were the pages where I did not notice at first that a frame of the dialog had a scrollbar, and I had to scroll to the right to see additional links, even though there was lots of space for them to show otherwise. A full manual is on the CD as well as on the web site.

Once set up I tested performance at a distance of about 25 feet through two walls. First I ran tests using the Netgear and then the TP-Link with the same remote server. The TP-Link delivered speeds 30-50% better than the Netgear on both the 2.4GHz and 5GHz bands. The Netgear is very good about coverage in my house - it has eight (I think) internal patch antennae where the TP-Link has three, rather tall stick antennae. I found coverage to be at least as good as the Netgear, even about 50-60 feet away and through multiple walls. I could only go by "bars" of signal strength but it seemed to me that the TP-Link's signal was stronger on both bands. Many dual-band routers are particularly weak on the 5GHz band.

As the three antennae suggest, this router supports the "3X" mode of some Wireless N adapters for a theoretical maximum bandwidth of 450Mbps on the 5GHz band and 300Mbps on the 2.4GHz band. Add those together and you get the "750" emblazoned on the router. The spec sheet I got indicates tested speeds of 241Mbps and 135Mbps respectively, still not shabby. The Ethernet ports are all Gigabit, and the test indicates LAN-WAN speeds as much as 935Mbps. That's fast.

The TL-WDR4300 has two USB 2.0 ports on back. These can connect to USB storage or to a USB printer. For storage the router will make the storage available as a network share, or you can enable an FTP server that can, if you wish, be accessed from the Internet. (The default is off.) Unfortunately, only standard FTP is supported, not SFTP over SSH, so your login information (you can set a username/password pair) is sent unencrypted. My advice is to NOT use this feature over the Internet.

I did not test the print server, as my printer is already network-enabled. For Windows there is a utility you install that, if I understand correctly, pretends to be a USB port and relays information to and from your USB printer. Scanners are also supported.

I did test the DLNA media server. You can specify up to six folders on the USB storage to serve and it will relay audio, video and photos to DLNA clients on your local network. I fired up Goodplayer on my iPad and played a movie from a USB hard disk - it worked beautifully. The promotional material claims that it can serve media over the Internet, but I think this is incorrect - there's no setting to enable/disable it and no instructions for how you would access the media from outside your local network. I will verify this with TP-Link support and update this review when I learn more. (Edit: TP-Link confirmed that media serving is local network only.)

TP-Link's documentation takes the unusual step of saying that one can install and run the freeware DD-WRT router software on some of its routers. I checked at the DD-WRT web site and while the WDR4300 is not yet officially supported, there is a beta version that at least partially works, and development for the WDR4300 is proceeding. According to the spec sheet TP-Link included, the WDR4300 has an Atheros chipset that runs at 560MHz, 128MB of RAM and 8MB of flash - these are rather high values for routers in this price range and suggests great performance and resistance to locking up after being on a long time (a problem I have seen with other routers.)

Lastly, as I do for most products I test, I looked at power consumption. For a device you'll leave on all the time, this can matter. I was pleased to see that the WDR4300 maxed out at 4 watts with wireless on, where the older Netgear router was averaging 6-7 watts. Excellent.

Not only does the TP-Link router seem well-designed, but their web site is easy to navigate as well, unlike those of some more well-known brands.

[Edited February 6, 2014 to note that Guest Mode was added after my initial review.]

4Lots to Like (vs. an old WRT54G)
By C. MacPhail
.
A few points that may not be covered in the other reviews...

- - - Good documentation - - -

The 125-page PDF User Guide seems well written and helpful. The setup wizard tries to be very clear and helpful, (but was not quite helpful enough for me -- see Note 1). The administrative interface is good at explaining many of the options instead of just labeling them. (Example in Note 3). If your router-IQ is low-to-medium, this is worth a lot.

- - - Bad documentation - - -

The setup wizard **does not urge or remind you to change the admin password**. It ends with "Congratulations...Enjoy surfing the Internet." (see Note 2)

Also, TP-Link provides no clarity on where their router stands with WPS. That's the convenient but very hackable device pairing procedure that some experts say should be disabled. (see Wikipedia: "Wi-Fi Protected Setup")

- - - Good Support - - -

Mac computers don't self-discover a USB file share on the router. I emailed TP-Link and got an answer 6 hours later. (Finder...Go...Connect to Server...smb:192.168.0.1/volume name)

- - - 2.4 GHz vs 5 GHz - - -

Apparently 5 GHz is ideal for apartments (where interference is the main problem) and 2.4 GHz is better in larger homes (where range is the main problem). You can set it to use either band, or both. (See Note 3)

- - - Energy savings - - -

It runs much cooler than my old Linksys WRT54G. Uses 3.95 watts vs 5.85 watts. Sounds trivial, but over 5 years it will save me $27 -- 40% of the router's cost. (see Note 4)

- - - USB ports - - -

A lot of routers have them now. This one supports printer sharing, and file sharing on USB sticks or USB hard drives. Local sharing is file storage and/or media server. Internet file serving is provided by FTP (File Transfer Protocol). Models like ASUS RT-N16 have direct Bit Torrent support in addition. Nice to have stuff available 24x7, even when various PCs are shut off.

- - - Improved Range - - -

I used the free and very cool NetSpot software (Mac only) to map WiFi signal strength throughout my house... TP-Link TL-WDR3600 (2.4 GHz band) versus Linksys WRT54G. The TP-Link lit up some difficult rooms that were marginal with the Linksys. A very measurable difference. Turns out we don't need two routers, just on decent one.

- - - Summary - - -

Router-world gets cheaper and better every year. I don't know if this one is the very best choice, but there are a lot of reasons to upgrade an old router.

- - - Notes - - -

Note 1: I kept failing the wizard's "Verify Router Settings" check. I had taken a little shortcut that seemed harmless, but wasn't. Instead of wiring my desktop PC directly to the router, I connected through my LAN, which had other devices also powered on. The presence of these other devices during setup apparently threw something off. If your desktop computer is 30 or 90 feet away from your cable modem, you could fall into the same trap.

Note 2: It says "The Easy Setup Assistant has completed a basic configuration of the router. For more advanced settings, please log in to the Web management interface." But that interface has 30+ screens. The average user should be told and guided to set a new admin password.

Note 3: Here's an example of the helpful stuff in the router management interface...

Advantages of 5GHz:

The 5GHz band is less likely to be congested. The 2.4GHz frequency range is much more prone to interference, as it is commonly used by other wireless networks in the area, as well as cordless phones, garage door openers and other home appliances and consumer products.

Disadvantages of 5GHz:

In general, the higher the frequency of a wireless signal, the shorter its range. Thus, 2.4GHz networks cover a substantially larger range than 5GHz wireless networks. In particular, the higher frequency wireless signals of 5GHz networks do not penetrate solid objects nearly as well as 2.4GHz signals, limiting their reach inside homes.

Note 4: That arithmetic is for parts of California, where marginal cost is $ 0.33 per kilowatt hour. If your cost is $ 0.11, your savings would be about $9 over 5 years. (1.9 watts * 8760 hours * 5 years * $ .00011 per watt hour.) 3.95 watts is when running 2.4 GHz band only. With both 2.4 and 5 GHz bands running it's 4.35 watts.

4Good performance, but worrisome pattern of firmware updates and nervousness about security
By Douglas B. Moran
I am currently happily using this WiFi router, but my concerns about its security caused me leave my previous router between it and the Internet.

PRELIMINARIES:
0. Recognize that Amazon has mixed together reviews for a range of different models in this product family -- models that have very different performance, design, features, ... So check that the review is for the model you are considering.

1. Recognize that many of the earlier reviews here contain obsolete information -- problems that have been addressed by firmware upgrades. The 2013-March-19 upgrade added Guest Networking and fixed some other problems. The previous upgrade of 2012-Dec-25 fixed many bugs and performance problems. Having seen the earlier reviews and being a curious techie, I tried the original firmware found that that the _sample_ of reported problems that I could easily test were indeed fixed by the 2012-12-25 firmware.
If you get this device, do NOT disregard these updates thinking that they are only optional (that is, only for those having identifiable problems).

2. (update) Don't stop at the firmware upgrade of 2013-March-19--it has a major vulnerability that is being actively exploited (eg, Web search for CSRF and "router hijack"). There is a subsequent firmware upgrade (2013-06-17) whose description makes it seem innocuous and unnecessary for most users, that update seems to block the version of this exploit that I have access to.

3. The pattern of firmware updates is worrisome. Some of the problems fixed are to be expected: performance problems/enhancements and compatibility problems with certain other network devices. For these, I applaud the manufacturer for putting out fixes on a 3-4 month time scale. HOWEVER some of the other problems are things they should have been correct in the initial release, and consequently I worry about undetected/unfixed problems that remain, especially those related to security since that is a critical function of this device (more below).

In this review, _Security_ comes at the very end for compositional reasons, not because it is low priority.

----
My Background: I evaluate home WiFi Routers on three basic criteria: Security, Performance, and Features, and in that order. I place "Features" last because most home users, and me currently, will not need or use most of the more advanced features. I worked in computer/network security in the 1990s and early 2000s and computer networking starting in the 1980s. Being retired, I now have too small a set of devices to evaluate this router for more sophisticated or demanding settings.

Because friends and neighbors ask for help in setting up/fixing their network problems, I am also exposed to the perspective and choices of the typical home user. This review contains elements of interest to different groups: experts, mass-market consumers,... I have tried to structure the review to simplify your quickly ID'ing and skipping elements that are irrelevant to your interest/experience (not needed, too complicated, too trivial, ...).

Features: Summary: The features are as expected for this class of device.

This is unsurprising because this is largely dictated by the chipsets used, and there is relatively modest variability across the competing chipsets at any given time. Because the landscape is ever changing -- what the newest chipsets provide and what device is using which generation of chipset -- my advice is that you use web search to try to find the chipsets used by the various models of router you are considering and if successful look at the reviews of those chipsets as a precursor for comparing the overall router.

The software used in many brands of routers also comes from common software code bases (via different paths) but many manufacturers try to obscure this. And there are various combinations of components, versions-used and customizations-make. While the manual available for download is only minimally out-of-sync with the firmware, the documentation of some of the features is underspecified and can be resolved only through experimentation. But this is quite common for this class of device (not just this model or brand).

The USB printer port worked for my printers -- a Canon MFP and 2 different models of Samsungs. This was only a brief test because the primary printer and the MFP also have Ethernet interfaces (preferred). The utility program was easy to use and worked well.

The USB storage sharing feature also worked, although I don't expect to be using it -- no current need and concerns about the security of the implementation.

WiFi Performance: Good
Background: This is replacing a six year-old Buffalo Airstation WHR-G54S with its omnidirectional 2.2dBm antenna replaced by a Hawking Directional 15dB Corner Antenna (Model HAI15SC). I live in an old house that was extended and remodeled several times by previous owners. There are enough perplexing weak/dead spots in my house that I cannot project performance to more conventionally constructed houses.

I tested locations in and just outside my house using the (free) inSSIDer software tool with both routers within 3 feet of each other. In the 2.4 GHz band, the signal strength was equal or slightly better than that of the (enhanced) previous one. Of course, the difference between G and N protocols and 40MHz wide channels improved throughput considerably. For the 5 GHz band, I had no comparables.

I got about 8 Mbps speeds when connecting from across the street -- about 140 ft with some intervening tree foliage. The router is in a front room, but not near a window and my computer was just inside the neighbor's front window.

In the month of use, I have had no problems with the WiFi. No freezing. No unusual patterns of delays or larger latencies. My primary computer is in a separate room, through an open door but well out of line-of-sight, about 30 feet straight line distance.

----
WiFi antenna geometry and separation:
This device has detachable antennas, allowing those that understand optimization of antenna geometry to do so.

Additional spec: Antenna separation: 85 mm (left to center), 98 mm (center to right), 183 mm (left to right).
FYI: For the 2.4Ghz band, the wavelength is roughly 120-125mm; for the 5.0Ghz band, it is roughly 51-58mm.

Background: For a multiple antenna system (such as this), the geometry and separation of the antennas can have significant effect, but I don't know what scheme(s) this device uses and I am too out-of-date to judge whether this device has antennas that are positioned for performance or for manufacturing convenience. Example, one long-established multi-antenna scheme, "Diversity", benefits from having its two antennas separated by one wavelength.

----
Temperature: This device stays cool -- very close to ambient temperature. I have it in a fairly typical location: an out-of-the-way location on a table top that gets somewhat below-average air circulation. Explanation: Heat is a concern because it shortens the lifespan of electronics.

----
Auto-selection of WiFi channel and channel width: This is relevant primarily to a WiFi router that might have another such device placed close to it, such as in neighboring apartments or companies or departments in a suite of offices. Or not, depending on the nature of the walls in between. I live in a dense suburban setting, with my immediate neighbors' WiFi routers about 50 feet from mine, and we have yet to see any signs of interference (unsurprising based on the literature and my measurement of their signal strength as less than half of mine).

Auto-selection was designed for situations where good-enough could be achieved without _careful_ coordination, or where such coordination was impractical (difficult neighbors, rapidly changing environment,...) In these situations, a common practice is to periodically check for _significant_ channel selection conflicts and make appropriate adjustments (manual selection, coordination, increase distance of router from conflicts,...)

I experimented using my previous WiFi-G router to create conflicts, manually setting its channel to the three non-overlapping channels (1, 6, 11) to see how this device responded.

The auto-selection of channels seems to occur only when the router is booted. This is expected because many WiFi adapters (clients) have difficulties or failures if the channel is changed while connected. Usually, it made a non-conflicting choice, but twice it auto-selected channel 6 when the WiFi-G router in the same room was already on that channel, but without any transmissions with its client beyond keep-alives. When the WiFi-G router was on channel 6, this router would predominantly choose channel 11 although I couldn't detect any reason for it to prefer 11 to channel 1.

With auto-selection of channel width, I observed the width change a few times (using the inSSIDer tool) but I don't have the tools for a meaningful test.

----
Utility programs: Download the updated versions.
The EasySetupAssistant utility was fatally and opaquely confused because I connected the new router to a second Ethernet interface on my computer. It seems to do little other than prompt for basic configuration, minus the critical step of changing the default administrative account and password. My recommendation is to start with Web browser interface.

----
Mounting:
Although most people will have this device sitting horizontally, there are slots in the bottom to allow it to be mounted vertically (eg a wall), but there is no stand. The slots are designed to force nose-down or nose-up mounting because of the multi-antenna system. There is a very slight tilt to the indicator panel (on the front), but not enough to enable _easy_ reading when mounted vertically -- while I can see the _presence_ of the lights, I have to put my head close to the vertical surface, or use a mirror, to identify the icons.

----
User Interface and documentation:
The Web browser interface has a panel on the right providing a significant amount of documentation of features being configured, and typically is close to what is in the manual. While this is good for the UI, it represents a deficiency for the manual. The documentation goes beyond simply providing a few words to disambiguate the labels in the setting panels, but routinely falls short of giving the user enough information to make informed decisions. Examples:
1. On selecting what protocols to use, it says that if all your devices use "N", you can select "N only". It fails to mention that selecting "N only" is likely to improve performance. Consequently, the user is likely to unnecessarily leave the default+recommended setting of supporting all protocols on that band.
2. The router provides SW and HW NAT, but doesn't say why you might want to turn off HW NAT (Answer: There are some some devices/apps, particularly older ones, that don't conform to the assumptions built into HW NAT. If such are having problems connecting out to the Internet, try turning off HW NAT to see if that fixes the problem. Otherwise, leave it enabled).
3. "IP & MAC Binding": The explanation in the UI fails to distinguish this from "Address Resolution" under "DHCP". Most users will want the latter, but since it is buried one-step down whereas the former is in the LHS tabs, it is easy to pick the wrong one (a confusion that can be seen with web search). Furthermore, this name is ambiguous, covering a range of capabilities. One use involves preventing ARP spoofing. Another simply improves efficiency.

In most places, the UI does a very good job of providing error messages and warnings (eg need to reboot before settings take effect) and of indicating why a selection isn't available (need to enable X). However, there is no warning that when you install new firmware, all your settings will be lost (so first you need to back them up, then restore after the upgrade).

The quality of the writing in the documentation -- grammar, spelling and content -- was significantly better than I have come to expect for this type of product. The few passages that struck me as "bad" were in fact typical of what I encounter in many similar products (from China) -- awkward, but not unmanageable.

----
UI Annoyances:
The layout assumes that the browser window will be very wide, with things such as excessive space between columns obscuring that you need to scroll to find additional columns with important settings.
Significant amounts of the available status information is not under the "Status" tab, but under the tabs for the associated settings.
MAC addresses have to be in the hyphen-separator format whereas most of my MAC addresses used colons, thereby inhibiting cut-and-paste. I did a cut-and-paste of those addresses into a TXT file, then a search-and-replace, and then a cut-and-paste into the UI.
Some of the log files have Internet addresses in hex rather than dot notation (a0b0c12 for 10.11.12.18).
Lack of inheritance. For example, for entering addresses on the LAN, rather than providing the subnet address and having you enter just the host component, the UI has you enter the full address and (correctly) gives you an error message when you make the inevitable typos.
No uploading of tables: There are tables of data (address mappings, rules) that need to be entered manually that I would like to be able to upload from a TXT file. If you are trying to manage multiple routers, having such makes it much easier to keep all properly updated (no missing entries, no typos from manual entry).

************
SECURITY ISSUES

1. There is no provision for signing off from the administrative interface despite it being a basic security practice to absolutely minimize such connections. There has been a long, long string of exploits that hijack such connections. Of most relevance to the current home user, there is a class of malware that you unknowingly download from an infected web site and if this malware finds an open connection to your router, it modifies the configuration to let the miscreants take over your network.
ADVICE: Do not enable automatic supplying of account or password. The session is _not_ ended by a soft reboot (needed for many setting changes) nor by closing the tab in the browser (tested: Chrome, Firefox, IE10). You need to do a full restart of the browser or, better yet, power cycle the router.

2. Administrative account name and password need to be changed immediately. Both are well-known and are the first ones guessed. If the malware cited in (1) does not find an open connection, it tries to open one and the defaults make it trivial. Other malware that gets on your network will often try the same.
2a. The EasySetupAssistant does not prompt you to change these.
2b. To change this, you need to open the last tab "System Tools" and select "Password" (seventh entry).

3. The USB storage feature comes with an administrative account with the same first-guessed username and password, and with read-write access (shudder). As part of this, you can enable the router to be an FTP server, and make that FTP server accessible over the Internet. I RECOMMEND _AGAINST_ THIS -- see Appendix.

4. Protection from Denial-of-Service (DoS) attacks is turned off by default (under tab Security, under Advanced Security) and requires that you also turn on "System Tools" -> "Statistics" (there is a reminder in red of this). I do not understand why this wasn't enabled by default: My router logs show a set of ICMP/TCP/UDP flood attacks every day or two (much reduced frequency from several years ago) and NMAP probes (the documentation is silent on this).

5. The TFTP ALG (Application Layer Gateway) is enabled. TFTP is a badly obsolete protocol -- it lacks authentication and was designed for devices with miniscule amounts of memory and processing power. For at least 20 years, the widely accepted firewall rules haven't allowed TFTP except on the LAN. This makes me very nervous about all the invisible security decisions embedded in this product.

6. I could not find documentation of what firewall capabilities this router provides, leaving me to make inferences from similar products and the details of how to loosen the firewall security. I don't like having to make inferences because they can too easily be wrong.

7. The description of the 2013-March-19 firmware update includes "6. Fixed some vulnerabilities and improved security". For a device that has a crucial security function in my network, I want to be _notified_ of fixes and not have to periodically check the manufacturer's website to see if there are new releases. I couldn't even find where to register my purchase to enable them to send such notifications. Unfortunately, this failing is common in this category of devices.

And more questionable default settings (this review is intended to give you a sense of the product, not a tutorial).

---- Appendix: Security issues of an Internet-accessible FTP server on a router ----

The USB connectors on this router can be used for USB disks (Flash drive, HDD). The router can be configured to allow access from the WAN (referred to as the "Internet"). Do _NOT_ enable this unless you fully understand your situation and the serious risks (for example, the WAN port is connected to a LAN you control and/or trust). For virtually every use, collaborative storage in the Cloud (Google Drive, Microsoft's SkyDrive,...) is a better alternative.

1. Do you trust the implementation of the server? Among FTP server implementations, there is a long history of exploits that allowed miscreants to:
1a. break out of the FTP directories and modify system file and take over the whole system (your router).
1b. override access controls -- add or modify files when they should have read-only access. If you must do this, at least use a USB Flash Drive that has a physical read-only switch.

2. Do you trust your ability to select account names and passwords that will stand up to a concerted attack? If so, the empirical evidence is that you are fooling yourself. Realize that large sites protect against these attacks with additional software (Intrusion Detection Systems).

3. Do you think that because you have a home network of 1-3 computers, the miscreants won't find you or bother with you? Wrong. They have automated "bots" (software robots) constantly looking for precisely this situation because of the higher chance of success.

Why worry about someone out there on the Internet storing files on your FTP server without your knowledge/authorization? Think child porn. Law Enforcement Organizations (LEOs) in their ignorance and enthusiasm still routinely fail to consider other options for how such files might wind up on your computer. This is not "simply" a matter of time in jail and huge legal bills before the matter is sorted out, or of lingering damage to your reputation. During raids, the LEOs have a tradition of administering "rough justice", including things like allegedly throwing the handcuffed suspect head-first down stairs (the traditional "He tripped") -- this is a famous, widely-used motivational/cautionary story from WiFi hacking, but equally applicable to FTP servers.

5Great Product, & Easy to Install
By NetworkWraith
I have used lots of Memory modules over the years, and Corsair has come to be one of my top choices when making a purchase. I recently obtained the Corsair [Apple Approved] 8GB Dual Channel DDR3 1066 PC3-8500 DDR3 Memory for my Macbook Pro 13" (Late 2009 - 2010 model). The memory itself worked on boot up no issues, and as far as the installation on the macbook pro, its not so bad. Granted the install is a lot different than that of the white MacBooks, but it is still pretty simple. All that is required is a small screwdriver and some patience. There are many tutorials on how to do this on Youtube, pretty much its as simple as removing 10 little screws (I would highly recommend keeping them in order, as at least 3 of the screws are longer and must go back in specific holes) and having somewhere to place them safe so they don't fall or get lost. ** Of course as always due care is required when touching or changing components inside your computer, things like a simple static charge on your fingers can be an issue (like when you rub your socks on the ground and shock your friend... not so funny with a computer) **

One thing that I noticed while installing my memory, is that the memory type required by the macbook pro changed sometime between 2010 and 2011 so you may want to verify your memory type in "System Profiler" which can be found in your Utility Folder on your Mac. That will usually tell you how much memory you have and what type (i.e. DDR3 1066, or some other type). If you need to know your maximum allowable/recognizable memory, I would recommend searching your model number on Apples Support page.

As to system speed improvements going from 4GB to 8GB of memory, I have noticed that my multi-tasking does not slow my computer down as much, and some programs seem to work a little bit better with the extra memory.

MacBook Pro 13"
2.53Ghz Intel Core 2 Duo
8GB 1067 MHz DDR3 (The RAM I purchased and took out of my laptop was "1066", but the OSx calls it "1067" not sure why)

3Dead after two weeks
By JD
RAM worked very well in my MacBook Pro, easy installation, went without a hitch. Two weeks later I'm watching a movie and my computer goes into Kernel Panic, giving me a flashing grey screen and to restart. Turns out the RAM died WAY too quickly-and I'm very careful with my computers. Amazon was great about the exchange, had new parts to me the next day. Nice memory, pretty cheap, but definitely buy from Amazon and keep your package around...

5Great Memory From Corsair, As Usual
By Ed
Does your Mac only have 4GB of RAM? Upgrading the memory in your system is still one of the quickest and easiest ways to boost its performance. Buying it from a memory company instead of Apple will save you TONS of money. Though, unlike high performance desktop memory, there aren't as many distinguishing factors when considering which SODIMM to buy. Pretty much all the major manufacturers have similar stated performance specs, so why would you choose Corsair's Mac Memory Kit over the others?

PROS:
- Great price
- Tested at Apple's compatibility lab
- Proven reliability
- Excellent support
- Lifetime warranty

CONS:
- Hard to remove from packaging

INSTALL & MEMORY TEST
Installing the Corsair Mac Memory kit in a 15-inch MacBook Pro was quick and easy, though I struggled a little bit trying to remove the modules from the plastic packaging. The memory was immediately recognized by OS X and everything ran quickly and smoothly. Rember verified the memory size, type and speed. The Corsair kit also passed memory tests with flying colors. Check out the Rember screenshots I uploaded to Amazon.

RELIABILITY, VALUE & SUPPORT
The timing for the CMSA8GX3M2A1066C7 is 7-7-7-20, which is the same as the kits offered by the other manufacturers. So then why would you consider the Corsair memory kit over the others? The most obvious is price. The Corsair kit has a very competitive street price. Did you know that Apple charges $400 for an 8GB memory kit?!

What might be less obvious is that the Corsair kit has been tested at Apple's compatibility lab. This ensures that the memory you buy has actually been tested to work with Apple's products. Though I'm sure that kits by other manufacturers have been tested for compatibility, the fact that Corsair went through the trouble of testing their memory at Apple, provides extra peace of mind and tells me that Corsair is willing to go the extra mile for their customers.

Additionally, Corsair's top notch support is always something to consider. Sure, like Corsair, many memory makers provide lifetime warranties, but how good is their support and how simple is the RMA process? If your Corsair memory goes bad, getting a replacement takes just a few short steps and their turnaround time is very reasonable. If you're in a hurry, you can even request an advance replacement (provided that you give them a credit card #, just in case you don't return the defective memory).

CONCLUSION
You can buy memory for your Mac from anybody, but why would you? You'd might as well get it from a company known for high-performance, reliable memory, who actually tested their memory at Apple's lab. The 8GB Corsair Mac memory kit is a terrific value and I recommend it to anyone looking to maximize their Mac's performance without sacrificing reliability or top notch support.
