4understand the tradeoffs
By d
This unit gives you sine wave output with no frills at an attractive price.

Be aware of the limitations of this new model at its price point. This is not a desktop product, so don't expect extras like ethernet or coax surge protection. It is less capable than some other APC UPSs with equivalent VA ratings; for example, the SMC1000 is rated for 600 watts, vs. 700 for the SMT1000. It has a 2-year warranty, rather than the 3 year warranty carried by most recent APC products.

Most importantly, this unit uses the new "Microlink" protocol, and does not have an expansion slot for adding a UPSLink interface. This means it will never be possible to fully interact with this unit using open source software, such as NUT or apcupsd; you can only get the most basic information out of it, such as line power up or down. Neither NUT nor apcupsd will be able to query it for load, output voltage, recent events, or many other things.

If these limitations don't concern you, it's a good value, and is the lowest-priced APC UPS with sine wave output. It's perfect for protecting the availability of a small server.

I noted that another reviewer complained of noise, but mine is nearly silent except when operating on backup power.

5Good product, good value
By Tog
The "SMC" line differers from APC's "SMT" line mainly in that you can't plug in their $220 Network Management Card. If you will need that level of sophistication, by all means look at the APC Smart-UPS SMT1500 1500VA 120V LCD UPS System instead.

(Note that APC's older "SC" line that the "SMC" line has now replaced delivered an inferior type of power that only vaguely approximated, through a series of stair-steps, the smooth curves of normal power. The new SMCs deliver the same smooth sine-wave power as the SMTs, erasing the critical difference between the two.)

I've been buying APC sine-wave UPSes for around a decade now and have been very happy. They are smart looking and work well.

4Buzzzzzzzzzz
By Jeffrey Brown
This is a good UPS from a size, capacity, and functionality standpoint, and if you're going to put it in a typical semi-noisy office environment or a server closet, then it's great. But if you have a very quiet office, you'll hear a constant low buzz from the unit. I don't mean the inverter buzz while it's on battery (that's expected) or the buzz when it's recharging after an outage (also expected). But a constant low buzz while it's just sitting there stable. It's on the floor about 5 ft away from my ears, and it's annoying. Maybe I'll get used to it after a while and my ears will notch out the noise, but after a week of listening to it, I'm kinda disappointed. EDIT: Either I'm getting used to it or it's quieting down. It's noisiest when the line voltage is below 120 and the unit is boosting it. Acceptable!

5Could not have been easier!
By Meredith Norris
I have the technological aptitude of that of a delayed toddler, and I got this to work! I was able to hook my MacBookPro up to my TV without any problem.

I read a few reviews that said that they couldn't get the sound to play through the TV with this cord; however, I had absolutely no problem with this. For MacBookPro users, open up the settings and select "sound." Once opened, you can select for the sound to be played through your TV rather than your computer. Further, while in settings, select "display" and choose "mirror" and your TV will - wait for it - mirror you computer. The whole set up took less than 5 minutes.

I could not be happier with this product.

5Posh!
By Jose Herrera Vega
Didn't have much expectations on this cable, ordered it because it was cheap and wanted to check how good/bad it was. I was really surprised with the results, audio can go through the cable directly to the TV or I can reproduce it on my Mac, video is full HD 1080p, length is perfect.

It has been with me only for week or so, but so far it's a "must have".

5Great Price, Works Well
By Paolo Montenegro
I used this cable to hook my 27" iMac (mid 2011) to my 47" Samsung TV and it works really well. I had no issues and the picture quality is great. Beats buying the Apple branded adaptor cable.

5Awesome - easily the best mini bluetooth speaker available
By Clayster
After trying around 10 different mini speakers for my cellphone this my favorite. I also have the flip. This guy is not far behind the flip in quality and volume.

The rundown:

Just tried a bunch of these ranging from $20-$60:

HMDX jam bluetooth - third place - sounds awesome, it's the loudest of all tested as well. Great bass and does not distort too much at the loudest volumes. nice, solid weight. However a constant buzzing/fuzzy noise made this a no go. Also resets to 50% volume every time it is powered on and off just like all the others except the JBL. would be my second favorite if it didn't have the buzz. well priced at 35.

Satechi bluetooth audio cube - not loud at all, tinny sound, very little bass, sounds muffled. expected more from the large size of the unit(about 3.5*3.5") compared to others, and the positive reviews. looks cool. overpriced at 50 for sure.

Kinivo wired - not very loud but otherwise great sound. nice bass, clear highs. distorts a little at max volume. cool looking. great value at 20

Sharkk bluetooth - second place - a best buy at 27 bucks. sounds great, good bass, and not much distortion on max volume. not quite as loud as the jbl or hmdx though. bland looking. Comparable volume to most of the others though.

JBL micro bluetooth - my favorite - first place. stylish, great volume, clear highs and great bass. Very user friendly and uses a manual volume dial so each time you turn it on it is at the previous volume. most reset to 50% every time you turn them off and back on. Also can be used as a bluetooth adaptor/dongle where the 3.5mm out can plug into any home theater system. Nice spot to hang it up on a nail, making the sound project farther and louder. Also has a small flat area on the side opposite the hook so it stands up by itself and it doesn't fall over even at max volume with bass heavy rap playing, meaning you can aim the speaker. This actually makes the speaker louder than the hmdx for real world usage. With extremely heavy bass music the mids and highs "fade out" a little bit at max volume since a single driver can only handle a certain amount of range. Otherwise it does not distort even at max volume. pricey at 60 but worth it. great battery life too, more than the advertised 5 hours. Also, re-connects with bluetooth devices automatically when they come in range, so no need to manually reconnect constantly like with other speakers. Can daisy chain with other micros also.

August bluetooth - decent quality and bass, however distorts at fairly low volumes making it a no go. Similar to the sharkk in size, weight and sound.

Satechi BT wireless portable speaker - worst of all, distorts at the slightest bit of bass or volume. Instant no go and a rip off at 40 bucks. can also be used as a bluetooth dongle like the jbl though. Looks almost identical to the kinivo. has horrible buttons that perform multiple functions and are super sensitive leading accidental skipping of songs, turning off, etc. stay away from satechi.

Xmini - bluetooth drops easily. by far the lightest and smallest and has good sound for it's size but little bass and not too loud. If you want portability and lightweight this is the way to go. The alpatronix is small too but heavier. pricey at 40 for what you get.

Alpatronix bluetooth - sounds great, but distorts quickly with any bass heavy music. Also "walks" across the table with bass heavy songs unlike the others due to it's weight/bass ratio. Loud, like the jbl and hdmx. 40 bucks is too much unless you don't listen to anything but classical at low volumes.

5HMDX Audio JAM vs JBL Micro wireless
By W. Nurre
I own the HMDX Audio JAM Bluetooth Wireless Speaker and I just bought the JBL Micro Wireless speaker. I compared them by using 2 iphone 5 connected to the same song on youtube and played them at the same time. After fading the volume up and down on each speaker it is clear that even though the HMDX Jam is a little louder the JBL definitely a clearer and cleaner sound. I use this outside while working construction. All my coworkers are amazed at the big sound coming from this little speaker. It says it will last 5 hours but I have been using it most of the day on my 10 hour shift and I have not had it die on me yet. Maybe because we don't always play it at full volume. I love it!!!

5The Best Bluetooth Speaker I've Yet Found
By Stephen R. Finney
This is the 4th Bluetooth Speaker I've bought, and it buries the competition by a significant margin. One of the earlier Bluetooth speakers I bought was the Cambridge Soundworks Oontz, which by comparison, falls way behind the JBL. The Oontz almost completely lacks in any of the lower frequencies, and doesn't greatly impress me in the rest of the sound spectrum. On the other hand the JBL Micro Wireless Bluetooth speaker has better bass, and overall, a much more realistic sound spectrum. Almost all smaller speakers, one buys, are going to be a compromise in some area. To have the desired portability, obviously you can't put a 12" woofer in such a speaker, but what you can do is maximize the frequencies that a portable speaker system can produce. JBL has done the best job so far. No, it isn't stereo, but how much stereo affect can you expect from a speaker you can hold in the palm of your hand? I read that one reviewer found that this speaker distorts. Well, any speaker, driven too hard, will distort. If you are driving a speaker that hard, you are in danger of blowing it's voice coil. Obviously, it's unrealistic to expect a speaker, the cone of which is around 2", to produce the level of sound of a bigger speaker. Physics can tell you why that is, but common sense should also. Within the reasonable realm of use, this speaker is, for now, the clear winner out of what I've experienced. The battery charge life is very nice also. JBL understates the expected duration of the battery charge life. I got probably more than 7 hours at a very respectable sound level. I also like the loop at the top of the speaker. With the loop, I can put a carbiner on the speaker, and suspend it from a belt loop. That enables me to carry it with me at work. Lastly, pairing with my I-phone was a breeze. Should I have trouble with any of my other Bluetooth devices, I'll amend my review. If you are looking for a great little Bluetooth speaker, with a long charge life, this is a wise choice. I can comfortably recommend it to anyone looking for a portable, Bluetooth speaker for their phone, or any other Bluetooth enabled audio device. Don't waste your time, nor money on the competition; this is the one to get.

***UPDATE***

After owning my JBL Bluetooth speaker for more than a month, I'd be prepared to give it an even higher rating, were one available. I'm still amazed, and was even fooled into believing someone was in an adjoining room, where I'd left it a few minutes before. I'd forgotten that I'd left the speaker on, and thought someone was having a conversation on his phone. That is the quality of sound that the JBL produces. I also have to say that the charge capacity is even better than I initially reported. With the volume turned all the way up, the speaker continued through the entire work day with charge left over If someone knows of a Bluetooth speaker with greater quality sound, given it's size and cost, I'd very seriously ask that they send me a comment to that effect. Finally,in my belief, the JBL Micro Wireless Bluetooth speaker is, if not the best of it's kind, I have yet to find a better one. You can buy this one, and know that it would be hard to do better.

***Second Update*** After more than 2 months my enthusiasm for this speaker remains as high as ever. I never cease to be amazed at it's charge life. Used at full volume for nearly 8 continuous hours, the speaker's battery still has charge left. I also have to agree with the others who praise the sound of the JBL Micro. While the bass isn't going to blow you out of your seat, for a very small speaker I still want to know if someone finds one that is better, especially at a non-astronomical price point. I'm sure there is one out there that sounds better, but is it as small, and is it's price as reasonable? I'll believe it only if I see it. Yes, IT IS THAT GOOD!

***Third Update**** My enthusiasm, for this speaker, just continues to grow. Last night, at work, my mp3's battery died on me causing me to have to plug it in to a charger. I wanted to continue to listen, and thought I'd give the speaker an opportunity to show how far I could go without losing the pairing between it and the mp3 player. At one point I was probably at least 75 feet away from the player, and the the speaker was locked on solid. Mind you this was line of sight, but at the same time, the building I was in was a crazy source of Radio Frequency noise. The range of a signal is a product of signal strength, distance, and other RF noise. AS the distance increases the signal strength drops, and eventually it drops beneath the background noise. The signal will keep on traveling infinitely, but will be of such a low strength that it will be completely overwhelmed by noise. I digress. The JBL Micro seems to have a robust bluetooth receiver in it, and is well capable of receiving a very respectable distance from the source. This is just another reason to put it on the top of your list of possible choices for a bluetooth speaker.

5The best multi port hub that I have seen
By Timothy B. Riley
Watch Video Here: http://www.amazon.com/review/R2ICWPTUICOGD I travel often and need to take a portable office with me. As a professional presenter and it seems like I am always making changes to my presentations right up to the last minute. I bought a mini hub similar to this one because I got tired of working with a limited number of USB ports on my travel computer. I purchased an unknown brand from a local store and it would not support all of the devices that I needed. As soon as I received this one I recreated the same situation that failed with my cheap hub and everything worked just fine. The hub supported my portable hard drive, a memory card and reader, a USB memory stick and my GPS. I had no problem at all running all of these devices through this hub.

When my other hub failed I when to the store that I purchased it from and they told me to call the manufacturer. It was a no-name brand and I couldn't find a way to contact them. I have never had a problem with a product that I have purchased from Amazon that they hasn't made right. I expect that since their name is on this product they would certainly make sure that I was taken care of if ever this hub failed. That means a lot to me as a consumer.

54-Port Hub Does The Job....
By Jeff Kraus
There really isn't a whole lot to say about a USB hub. Obviously, as the description states, it supports up through the USB 2.0 standard. It's extremely lightweight and small, taking up about half the area of an average smartphone. It has a single amber LED that lights when power is reaching it.

The hub works flawlessly for me. Since it has no separate power supply, its ability to handle higher-powered devices that draw from the USB cable is limited to the port you are connecting it to.

(Edit 03/22/11) ---------
I'm seeing some other reviews that aren't entirely accurate regarding the unpowered nature of the hub, so it's worth expanding on. The USB hub can handle exactly as much power as the port that it is plugged into is capable of providing. For example, many keyboards have a USB port that can be used to plug in a mouse. Generally that is a low-powered port that is incapable of running a portable hard drive, charging an iPod, etc. Plugging the hub into that port would present the same limitations.

On the other hand, plugging the hub into a port directly on the computer's chassis is going to provide significantly more power to the hub. Higher powered devices such as a DVD burner, hard drive, etc. will work -- provided they work plugged directly into that same port the hub is plugged into. And if multiple devices are connected simultaneously, the power they draw combined must still be less than the maximum power available to the port.
--------

I tested the hub in both Windows 7 (64-bit) and Fedora 14 x86_64 Linux (on a dual-boot Dell Inspiron 15R) with no problems whatsoever. No drivers are required, so it's effectively a seamless addition to any system. Plugging in a USB memory stick or 500GB WD Passport portable hard drive resulted in the item in question being mounted exactly as if the hardware had been plugged in directly. A quick throughput test showed that the hub was perfectly capable of handling the 500GB Passport drive while it was playing a 720p high definition mp4 video.

I docked one star for the price, which at the time of this writing, is shown as more than double the price of other functionally equivalent mini-hubs such as the Belkin 4-Port Ultra Mini Hub and the Connectland CL-U2MNHUB-4B 4-Port USB Mini Hub. If the price goes down to something that is more in line with these other hubs, I will amend the rating.

Other than the price though, I found no issues with its build, functionality, or usability. If the cost comes down I can honestly, whole-heartedly recommend this hub.

*** Update 08/06/2012 *** The price has indeed gone down by more than 50% since this review. As such, I have amended the rating as promised. Oh, and the hub is still performing as it was when I originally posted the review.

3Problem when used with USB audio
By RKL
This hub seems to have a problem when an USB audio device is connected through it. If there's any electrical power line interruption (fridge starting), it causes a drop in the audio. For all other uses, it worked fine.

Honestly, many hubs seem to have this issue, including the Pluggable and CablesToGo ones. The Belkin and the one built into my Dell LCD monitor do not seem to have this problem. (I've bought a lot of hubs looking for a good one! I knew they exist bec my Dell LCD's built-in worked but I needed one for a different PC.)

It must be a matter of one chip set vs another but I do not know which chipset is in which hubs.

And yes, I do have some decent power filters / voltage regulators, but they don't respond quickly enough to short drops in voltage. (Online UPS would work fine but those things are noisy!!!)
