5Well built, good camcorder
By M. Montana
I record a LOT of live performances, where its typically very dark, with fog and flashing lights/lasers. I think this is the most extreme that anyone could ever hope to record on a budget of under 20k. The G10/G20 are the ONLY non-pro camcorders that are usable for this. I have 4 camcorders total, so I will compare/contrast them in the context of how I use them.

1) Canon g20. G20 is essentially a g10 that has been fixed. Audio is MUCH better, Digital zoom has been removed (it was useless on the g10), Telemacro has been added. Powered IS has been moved to the touch screen and replaced with a 'Pre-Record' button (but this is changeable in manual mode), the low light seems a tiny bit better, side by side the g20 looks a tiny bit brighter than the g10, but where it REALLY makes a difference is the noise in the video. Shadows are cleaner/crisper.

2) Canon G10. This was the prime camcorder before I got the G20, I would try to hand record the entire concert on just this. With the other 2 camcorders as 'emergency backups' to clip to if I absolutely could not save a section of video (like someone walking in front of me, or a band member jumping off stage without me catching it). The Audio was beyond piss poor though, despite my best efforts it would always sound tinney, and lack on vocals.

3) Canon M30. I used this as the backup, Usually very dark and nearly unwatchable. Colors usually off. However, prior to the g20, this was the best source for audio, when connected to a shotgun mic. Audio is FAR better than the G10, but close to the G20.

4) JVC Everio 440US. Not even sure why I would bring this or set it up. Unless the lights were very bright, it just picked up noisy black, and the audio was tolerable, but far from good. It really was useless unless it was less than 2' from a person. During daylight its actually a GREAT camcorder, but has basically no low light ability.

I LOVE the new hood design, its nice having a cap built into the hood. Eye piece looks nicer.

Overall the g20 truly is a g10, specs are identical. I suspect there was a firmware update and very minor hardware changes to make the new model. I was actually trying to buy a second G10 when this hit the market. I was pleasantly surprised at the minor changes, but if you are buying this as an upgrade from a G10.... Maybe hold off till you can grab the g25 (pro model) or g30 (which supports 60p), otherwise you will likely be disappointed. It IS better than the g10, but not by enough to justify spending a grand to upgrade.

Some Misc info for people to consider buying with this:
58 mm uv filter (evena cheapo will be fine... just protects your lens from scratches/dirt/etc)
3000 mah wasabi extended battery pack, (works perfectly in this, shows time remaining, etc)
2x32 gig SDHC cards. Comes with 32gig built in, but its nice to know you have 3 separate places to record to. Plus the usb interface is slow for dumping video to a computer.

5Fantastic camera! You won't be disappointed!
By Oscar Wilde
Right out of the box, it seemed very solid and high quality which one should expect for the price. The new lens hood not only works better, but also looks a lot cooler. The touch tracking focus works great and is extremely useful. In low light this camera really is just amazing. It's much better for that than any dslr I've used. The image stabilizer is very helpful. I have compared it to my dslr footage and it is MUCH more stable meaning you probably don't need a shoulder rig. I just wish that the focus ring was not so hard to turn because some times i mess up the video when trying to turn it really far. The only advantage for me when shooting with a dslr is that you get manual zoom. But it's still fine with this camera. Also, the battery that it comes with is very small, so I would recommend buying some extras. The off brand batteries will work great and it's super cheap. But other than those two things, this camera is just perfect. If you aren't super picky about audio than this is fine. But if your in a production business and need really good sound quality, you should look at the xa10.

I was a little hesitant to buy this because I thought it was going to have a deeper depth of field according to what I have read about camcorders in general. Someone also told me that camcorders don't have a shallow depth of field. When I first took it for the test, i was quite surprised. The performance was really pretty good, so don't be too worried about that if you like a shallow depth of field. Using manual focus is great and I can get a lot out of focus.

I don't think that it's weather proofed, but i have never had a problem and am never afraid to take it out in some snow which I do quite often. Like I said at the top, it is quite solid meaning it's pretty heavy compared to the other camcorders i was looking at below $1500. So if you want to go skiing with it and put it in your pocket, it will weigh down your jacket. So bringing a backpack if your going skiing or for a hike is a good idea.

I love using dslr's and were used to them. But now I can never come back to dslr's. Using this camera is just so easy and simple. You can start shooting so quick. The start up time is pretty good, especially compared to dslr's I've used. I know that some nikon's have auto focus for video, but there is no comparison. The auto focus on this camcorder is lightning, and i never worry about it in low light. Also, most dslr's that do auto focus during video is loud enough to ruin audio. And obviously, This is completely silent. And this makes the camera just that more simple and easy.

I am very happy with the camera so far. I have tried to upload some test video but it said that it wouldn't except the format. So if you already have a g10, than it probably isn't worth upgrading. But highly recommended and you will most likely be satisfied.

4Great camcorder for the DSLR fan
By mkgraham
I thought I would never get a camcorder with all the high tech HD video modes of capture out there these days. I found using video on my Canon 5d mark II superb in quality but lacked real layman control. I missed being able to focus instantaneous in a shot and the form factor of a DSLR as a video camera definitely is not there for run and gun situations I am finding my self into chasing a 2 year old around. Sure you can spend money on an elaborate setup that can turn the DSLR into something like a camcorder but I like the compactness the likes of the G20 offered.

So enter the Canon Vixia HF G20. I was interested in a sub $1200 HD camcorder and I am always a first to want a new thing so in return, and you, get an early review having 2 weeks with it so far. From what I know the camcorder is exactly the same as the G10 predecessor except for the new HD Pro sensor that allows more light capture. So I preordered and at the same time ordered this great book (I know its for the G10 and XA10, but all the G20 has is the better sensor) - Professional Results with Canon Vixia Camcorders: A Field Guide to Canon G10 and XA10 Now with the camcorder, I am happy I have read the book and use little of the huge manual that came with the G20.

So far it has shocked me how well the camcorder takes video and although the controls do take a little time to master, the touch screen works well. Maybe they did improve on it from the complaints I read on the G10.

I did drop one star for two reasons. The battery that comes with it is terrible so you best splurge on the max capacity one Canon BP-827 Lithium Ion Battery Pack for Vixia HG, HF S & HF M Camcorders (Retail Packaging). Also I wish they included a shoulder strap to carry the camcorder around easily.

So I will promise to update in 6 months, but so far so good!

5Hands down, a GREAT Investment!
By J. Patterson
This flash is excellent for SO MANY REASONS! If you are just beginning in photography, you should check out this flash. If you are a pro and you need either a back-up, a slave, something to experiment with, and/or if you love to work in manual, you should check out this flash. Yes, it doesn't have any automatic functions, but for the price to feature ratio, you get more than enough to up your game with flash photography.

I have been shooting as a pro for about 2 years now. Before that, when photography was just a hobby, my first flash was the Canon Speedlite 270EX Flash for Canon Digital SLR Cameras. Even though it helped, it was not by much however, my knowledge of strobist photography was non-existent at the time. After a while, I graduated to the Canon Speedlite 580EX II Flash for Canon EOS Digital SLR Cameras. When I got the 580EX II, I realized that I missed out on sooooo much just shooting with the 270EX. In addition, I ended up getting a Canon 430EX II Flash and the Speedliter's Handbook: Learning to Craft Light with Canon Speedlites. After studying this book, my photography has not been the same since.

Even though I love my 580 & 430, I could not afford to buy 2 or 3 more of those flashes and even if a miracle happened, how much harder would it be for me to replace those flashes if one or more is lost or damaged. So I did my research and came upon the original YN560. For a cheap flash, it had the best reviews I came across, especially for a flash under $100. I was skeptical at first because I was so used to Canon equipment, however, I thought $70 couldn't hurt me tooo bad. When I finally got one I was COMPLETELY BLOWN AWAY!!!!! This is EXACTLY what I needed as a slave only flash! The build quality is similar to the 580, they take the same accessories, and it is just as powerful as the 580. I bought a second one that same day.

2 years after using the original YN560s, I saw that Yongnuo came out with the YN560III, which has a built-it receiver for the YN602/603 triggers! At one time, this flash wasn't in stock for almost 2 months because they were selling out SO FAST! As soon as they were available, I purchased as many as I could since demand was and still is crazy for this flash.

If you are a pro looking for a cheap flash, here are my reasons why I would recommend this flash to you:

1. YN560III has a built in radio trigger, which adds a crazy amount of convenience to your workflow!
2. YN560III has also 2 built in optical slaves modes, 580 has one but is limited to work with canon flashes only.
3. Cheaper to replace & add additional flashes.
4. Provides a sound when the flash has charged to fire again.
5. Similar build quality as the 580.
6. Accepts the same accessories as the 580.
7. Just as powerful as the 580.

If you are a beginner, and/or someone who is considering the cheap route when it comes to buying your first flash:

1. Built-In Radio Receiver.
2. The YN560III can be triggered by ANY on-camera flash, whether you have a professional camera or a simple point-and-shoot camera. Unless you have a Canon 7D or newer with a pop-up flash, triggering most of Canon's flashes have complex limitations.
3. Price to feature ratio.
4. Pretty much the same reasons why a pro would buy this flash!

If you are a beginner and are not aware of the 580EX II, it is a very good old school Canon flash. Take away the automatic functions and the weather sealing, you pretty much have the YN560III. If you are a pro, yet again, the YN560III is just a cheaper and manual-only version of the 580 (With a Built-In radio receiver!).

Also, as a comparison to Canon's new flagship model flash, the Canon 600EX-RT Speedlite Flash (Black), you can purchase 5 YN560IIIs plus a set of Yongnuo RF-603 C3 2.4GHz Wireless Flash Trigger/Wireless Shutter Release Transceiver Kit for Canon 1D/5D/7D/50D/40D/30D/20D/10D Series for the price of only ONE of Canon's own built-in radio flashes! Having an automatic flash with a built-in radio triggering system is AWESOME I must say however, you WILL PAY a large sum for Canon's system. Pretty much, five 560IIIs and one set of RF-603s is less than $500 total. 3 Canon 600EX-RTs and one ST-E3 transmitter is about $1,800 total! If you have the money and Canon equipment, go for the Canon system however, most people are like myself and cannot afford Canon's top notch system as of yet.

If you are a beginner, the reason why you want radio triggers is so your flashes can be triggered with fewer limitations. Triggering your flashes by radio waves is MUCH MORE RELIABLE than triggering them by a flash of light from a camera or another flash in general. The science and math behind how this works can get very technical and is much easier to understand if the system is seen in action. Check out YouTube for several examples of 'off-camera lighting.'

Also, for most photographers using off-camera flashes, you had to at one time, have a receiver for every flash you have; (You still do in some cases.) If you have 4 flashes, you would have to buy 4 receivers and also have a trigger on your camera. With the YN560III, you now only need one RF-603 Transceiver (a receiver & transmitter built into one device), which is awesome since you are saving money and also, you don't have to buy extra batteries for those receivers you would have needed before! NOTE: RF-602 and RF-603 triggers from Yongnuo are the only triggers compatible with the built-in receiver inside this flash. I hear that the RF-604 X2-C Wireless Flash Trigger for Canon EOS 1D series, 5D series, 7D, 6D 60D, 50D, 40D, 30D, 20D, 10D, 650D 600D 550D, 500D, 450D, 400D, 350D, 1000D Powershoe G10, G11, G12, G15 G1X SX50 may be compatible as well. NOTE: If you decide to purchase the Meyin 604, I hear that it only works on channel 16 with this flash, which might be a deal breaker to some ;-).

For a lot of situations, I only need to shoot with the YN560s. If I needed to have an automatic flash, my Canon flashes will do just fine. Also, I like the challenge and consistency of shooting in manual.

The YN560s work really well at weddings & events when you need multiple off-camera flashes to bounce light off of the ceiling to illuminate dark venues. Because they are relatively in expensive, being able to purchase multiple YN560s take the stress out of shooting in poorly lit conditions. Also, I've found that the more flashes I have, the more creative options I have like overpowering the sun, applying color gels, etc! Make sure you look up tutorials and books on strobist photography to learn this stuff! :-)

Truly, these flashes are one of THE BEST INVESTMENTS I'VE MADE TOWARDS PHOTOGRAPHY! I'm very grateful to God for being able to share some knowledge with you! I hope it helps. Take care and happy shooting!

5Comparison to YN560 (mk I), Canon 580EX II
By MiRSD
EDIT: A problem that I didn't experience at first - while the LCD screen is bright and easy to read in most situations (looking straight at it), I found out that it's not so easy to read from other angles. For example, if you put it on an umbrella swivel (for an umbrella, beauty dish, softbox, etc..) and have it angled it can be impossible to read. If tilted 90 degrees forward, it appears as if everything lights up on it (the LCD screen uses something similar to a digital alarm clock - so it looks like "1/188" which allows the "88" to light up certain parts to form different numbers. So it could be 1/1, 1/2.. 1/16, 1/32, 1/64, 1/128) Again, the problem is that at odd angles (like 90 degrees forward) it appears as "1/188" instead of what the actual power is. On the other hand, tilting it 90 degrees backwards it will look blank.. so the viewing angle isn't great and creates some readability issues. Another example is if it's sitting lower to the ground and you're looking at it from a standing height it will appear blank. You need to bend down and look at a better angle to see the actual power. This could be considered a big downfall for some and does show that there is an advantage to the original YN560's LED system.
For comparison, the Canon 580EXII does have a similar issue but not nearly as bad. Tilting it 90 degrees forward it is still easily readable.

Over the last couple years, YONGNUO has made a name for themselves in the photography world. They've released some very nice, high quality alternatives to the "name brand" products out there as VERY nice prices. One of their better lines of items are their Speedlites (portable flashes).

I own and use many of their Speedlites - the YN460, YN460-II, YN465, YN560 and now the YN560II. I've used them for years and they all still work perfectly (the only issue was with a YN560 (original) that arrived with a broken zoom). For the prices they sell for, I find them to be very reliable. I have dropped them onto concrete from small heights (2-3 feet) and they continued to work fine.

Owning several of these, I'd like to compare them for anyone who was in the same situation as I was when looking for a flash. For the record, these units were purchased for:
YN560 - 70 bucks
YN560II - 100 bucks (NOTE: That was the price from a US Seller. From China they can be found for about 70 bucks, the same as the YN560)
580EXII - 500 bucks
Design:
Right off the bat, all 3 pretty much look the exact same. YONGNUO basically made a copy of the 580EXII mold (right down to including fake buttons on the sides which are REAL buttons on the 580EXII). The nice thing about this is that it means all accessories designed to fit the Canon 580EXII will work just fine with the Yongnuo YN560 (and 560II).
The obvious difference is the back of the flash. The original YN560 uses a LED system to indicate the power and zoom range - this means if 1 LED is lit, it's 1/128 power.. if 2 are lit, it's 1/64.. 1/32.. 1/16.. 1/8.. 1/4.. 1/2.. 1/1. This makes it easy to glance at from a distance and see "All the lights are lit, it's full power" opposed to an LCD screen which can be tough to read in the dark or from a distance.

LCD/Back display:
The YN560II and 580EXII use an LCD screen which tells you the actual power: 1/1, 1/2, 1/4, etc..
The better option for back display (LCD vs. LED Lights) comes down to preference - I have no issues with either. Both LCD screens (YN560II and 580EXII) have a backlight option - the Canon 580EXII has a specific "light" button which will turn the backlight (green) on for a few seconds. The YN560II will automatically turn the backlight (red/orange) on whenever any button is pressed. I like the YN560II's method as you can easily see the information no matter wherever you are when adjusting power - lit or dark areas (with the 580EXII you need to press the light button to see the light - so if you're in a dark area and changing power, you need to press the LIGHT then change the power (or vice versa) to see what level it's at - the YN560II will light up as soon as you start adjusting the power). The YN560II does not, however, have a dedicated LIGHT button but you can press any button (even the "enter" button which won't have any effect on the settings) to turn on the light for a few seconds.

The LCD screen on the YN560II is much more basic. You get the MODE you're in (M/S1/S2/MULTI (more on these later), the power (1/1, 1/2, 1/4...), the zoom level (24mm, 28mm, 35mm, etc..), the AUDIO indicator (more on this later..) and some others which will come on from time to time. One of the most helpful is the LOW BATTERY icon - unfortunately it doesn't give a constant indicator of battery life, only when it's "low". The 580EXII, on the other hand, has the same information but it's laid out in a much nicer presentation.
I will say that I prefer the YN560II LCD somewhat as everything is VERY BIG ON THE SCREEN. The power level is about 3 times as big as that on the 580EXII (so you can easily see the power level from a distance).. same for the zoom level. Doesn't look as fancy, but the information is easier to read on the YN560II. Again, the YN560 does not use an LCD, only light up LED lights - you can even say that the YN560 is easiest to get an idea of the power level from a distance since you can see how many LED's are lit from almost any angle.

Modes:
The CANON 580EXII includes: MANUAL, ETTL (automatic flash exposure), MULTI (a strobelight-like effect where you can control how many times it flashes and how frequently), a MASTER mode (to control other CANON flashes) and a SLAVE mode (to be controlled by a camera like the 7D, a transmitter like the ST-E2 or another 580EXII flash).
The YN560 and YN560-II include: MANUAL, SLAVE1, SLAVE2 (and the YN560II includes MULTI). SLAVE1 and SLAVE2 on the Yongnuo are nice as they let you trigger these flashes using any other flash (SLAVE1 is for other manual flashes (or flashes without an ETTL metering), SLAVE2 is for cameras that use ETTL metering). These are great modes to have and are not on the CANON 580EXII. On the same hand, the 580EXII includes the ETTL ("automatic") and High-Speed sync mode for the flash while the YONGNUO models are all automatic and do not include high-speed sync (YONGNUO makes the YN565 flash which does include ETTL, but not high-speed sync)

Power:
All 3 have roughly the same amount of power output. They can be adjusted anywhere from 1/1 (full power) down to 1/128. I believe some of the earlier Yongnuo flashes only went down to 1/64 power. You can also fine-tune the power, so if you want something between 1/2 and 1/1 power, you can set it to 1/2 and then add +0.3, +0.5 or +0.7 compensation - this is done with the up/down buttons on the YN560 and YN560II. It is MUCH easier to read on the YN560II since it will say: "1/2 +0.3" while the YN560 only has 1 set of LED lights (which display flash power output, zoom level and flash exposure compensation, depending which one you're looking at. The YN560II will display all at once).

FUNCTIONS:
All 3 flashes have a zoom function on the flash - the YONGNUO are the easiest to operate as they have dedicated +/- buttons (canon requires you to press a button first and then change the zoom).
The YONGNUO flashes also allow easier control of the power (also a +/- button while the 580EXII requires you to press the SET button and then turn a wheel). This is a toss-up on who wins - the YONGNUO ones are easier to adjust, but that also makes them easier to hit by accident and change the power levels when you didn't want to.

BUTTONS:
The YN560II and YN560 have similar looking buttons (rubber-like), but the YN560 buttons are somewhat mushy/soft while the YN560II has firm buttons which feel a bit nicer. Both are usable.
The YN560II uses similar buttons to the 580EXII, except the 580EXII uses a wheel instead of the left/right/up/down/SET button on the YN560II. I actually prefer the buttons on the YN560II as they're easier to pick up and use, but all 3 work fine.

CONNECTIONS:
The YN560 and YN560II have a metal hotshoe (the YN560 originally released with a plastic hotshoe, but was quickly replaced). They also use the turn-to-lock clamp for the hotshoe while the Canon 580EXII uses a rubber gasket with a switch you flip to lock it down (this also keeps it somewhat water-sealed on the hotshoe). I prefer the 580EXII style lock for sure, but the others do work fine.
All 3 have a PC-Sync input and a high-voltage battery socket to connect an external battery pack to (such as the CP-E4). I use the Pixel TD-381 battery Power Pack for for Canon Speedlites 580EX II, EX580, EX550, MR-14EX,MT-24EX, extremely stable fast recycle time 1.24S and highly recommend it! These greatly speed up recycle times and give you a longer battery life.

RECYCLE TIMES:
I loaded fresh rechargable batteries (same brand, all bought at the same time and freshly charged) into all 3 flashes, connected them to a radio trigger to set all 3 off at the same time. The YN560 recycled the faster (barely beating out the YN560II), and the 580EXII slightly slower than all 3. The difference was about 1/2 to 3/4 seconds difference between all 3. With the external battery pack (above) connected, all were fully recycled and ready for the next shot within about 1-2 seconds from full power (and all ready about the same time).

OTHER:
The YN560 and 580EXII both go from lowest power (all the way left) to highest power (all the way right) and stop at each. If you go to full power (1/1) and press right, nothing happens. If you go to lowest power (1/128) and press left, nothing happens. The YN560II changes this - if you go to full power and press Right, it goes back to 1/128 (and if on 1/128 and pressing left, it goes to 1/1). I'm not sure how much I like this, since you can easily change the flash power greatly without noticing it if you press a button.
All 3 flashes have a Pilot light which indicates Charging (green) and Ready (red). When ready, you can press the light in to trigger the flash -- this is very easy to do on the 580EXII and YN560II, but with the older button types on the YN560, it's a bit tougher.

EXTRAS:
The YN560 and YN560II have an optional sound function - this means you hear a "beep beep" when the flash fires and a long "BEEEEEEEP" when it's ready again. This is helpful to know if a flash fired (sometimes looking through the viewfinder you can't tell) and to tell when it's ready to go again (so you don't take a shot before it's charged). The 580EXII does not have this feature.
The YN560II seems noticeably louder than the YN560, making it somewhat hard to hear the YN560 (if using one of each flash) - it can also be quite loud if used in quieter areas (to the point you wish it had a volume control -- I never had this issue with the YN560).

The YN560II and Canon 580EXII include a nice nylon carrying pouch to hold the flash and the coldshoe (more on that later..), the YN560 just comes in a thin carrying bag.

All 3 include a coldshoe (so you can set the flash on the ground, standing up). The YN560 included a nice one with metal around certain areas (like the tripod threading) while the 580EXII and even the YN560II included an all-plastic cold-shoe.

All 3 include a wide-angle diffuser panel and a popout bounce card.

The 580EXII can swivel 360 degrees (180 degrees left, 180 degrees right), the YN560 and YN560 are limited to 180 degrees left or 90 degrees right.

So overall, what do I recommend?
The 580EXII is obviously in a different class (and a much different price range!). I didn't want to compare it against the Yn560II directly to determine which is better, but I owned it and wanted to throw in some comparisons - I'm not expecting the YN560 and YN560II to be the 580EXII, but they both held up very well against it (and even exceeded in some areas)!
Some of the features in the YN560 and YN560II are great, and not even part of the much more expensive 580EXII (such as the sound indicator, low battery indicator and slave-modes).
With both YN560 and YN560II being very close in price, it's up to you whether you find the few new features on the YN560II (the LCD screen and MULTI option) to be worth the extra money. I own 2 YN560's, a handful of YN460's, YN460II's and YN465's and am considering getting another YN560II due to the low price and great features. Highly recommended - either the Yn560 or YN560II.

EDIT: Just bought another YN560II. Love this thing!

4Great value in a manual flash
By Kian O'Connell
I haven't shot enough with it to determine consistency, but I'm pleased so far. Flash is a bit large for the output, but it is still decent. I did some test shots and was getting f8 at 18 ft. This tells me that the GN is just about 144. The specs put it at just 58. (Maybe that was supposed to be meters and not feet). This is almost as good as I got from the Sunpak PZ42XC at full on manual.
Build is similar to the Sunpak flashes. Swivel and bounce feel no less solid and click into place just fine without shifting. The built in diffuser AND mini bounce card are nice although small. My sunpak PZ42XC doesn't have that. There is a PC sync and a power supply connection on the side which my sunpak doesn't have either. Then there is the optical slave which works well with two levels of sensitivity and of course my sunpak lacks that as well.
With all of that said, this flash isn't for just anybody. This is just a plain dumb manual flash without TTL or even a thyristor. THERE IS NO AUTO FUNCTION. If your intent is to use this as a camera mounted flash for candids, forget it unless you know how to manually setup for every shot by adjusting your aperture as needed. It is not intended for that purpose.

The flash came with a base that has a threaded hole in the bottom so it can be mounted to a stand. It would do a terrific job providing fill or backlight capability. It swivels 180 degrees and straight up so bouncing into an umbrella or through a diffuser while the slave sensor faces forward for a stationary photo shoot are ideal uses of this flash. So is placing it behind a subject for a backlight. My Lumiquest gel holder fits very tight due to the large flash head, but it fits.

The controls and lights on the back seem a bit confusing and the manual isn't a lot of help since the translation from Chinese to English is about the same quality as you get from Google translate..... I was able to figure it out but it took some time experimenting with the unit.

Recharge is quick - even at full power. I was very impressed. Of course it has less output than the Sunpak and uses the same number of batteries but still, I was pleased.

One other note. When i first tried to turn it on it wouldn't do anything and I was immediately afraid it was DOA. I found that to turn it on, you must hold the on-off button for a couple seconds. When you press it down, the lights on the bar progress from left to right and if you don't hold it down till the lights get to the far right, it just shuts off. Awkward, but easy to deal with if you are aware of it.

Altogether, I'm quite pleased with what I have assuming it lasts a a while. The build seems solid so I'll just have to wait and see. I'm confident enough in the product that I'm going to buy a second one so I can have one for fill and the other for a backlight for impromptu studio shots.

If you need a slave flash with some power and manual controls I really think this is the best thing out there. Almost everything else in this price range is a single power or auto-flash without the ability to make manual output adjustments. You can get this output with no slave, the slave with no manual,or you can spend twice as much. But if you need a speedlight with auto functions for camera mounted shots, get something with auto functions.

3PNY 64GB USB Flash Drive
By Curious observer.....
Well I've been a loyal PNY product user for over 10 years, and I can honestly say, that their products have been reliable, functional, and have lasted the test of time. So as both of my 32GB flash drives approached maximum capacity, I found myself sifting through the web, in search of two 64GB replacements, at a reasonable price.

The price of memory is such a fickle thing theses days.... Much like buying a new car, what costs a fortune today, is worth just pennies tomorrow. Not wanting to pay a king's ransom, I managed to locate a distributer that was selling PNY 64GB Attaché USB Flash Drives for approximately $74 each. I bought two flash drives, from the merchant, and anxiously awaited their arrival.

When they showed up at my door, I found that PNY had made a few changes to their Attaché USB Flash Drive product line, since my last purchase.

1. The 64GB Flash Drives no longer have a LED activity indicator of any sort on the drive. I'm not quite sure how they expect anyone to know when their flash drive is being accessed. I, like many other users have come to expect, utilize, and some even require an activity light of some sort on their external devices. This omission was a major disappointment.

2. Over the years, I've found it necessary to reformat external storage devices, such as flash drives, and start fresh. This worked fine with both of my PNY 32GB Flash Drives, going all the way back to my first 256MB Flash Drive. Well this functionality has got an added rub with the 64GB Flash Drive. Apparently, the 64GB Flash Drive utilizes the exFAT system, which requires a patch/driver from Microsoft, before your Windows XP or Windows Server 2003 machine can `handle' the drive properly. Sort of pain, and no mention of this added requirement on the documentation or packaging the flash drive came in.

3. Lastly is the cheaper case & USB dust sleeve. The case is noticeably cheaper in heft. Seems like PNY elected to go with a cheaper grade of plastic, while at the same time updated their design to incorporate a capless dust sleeve. I say sleeve, since it clearly only protects the sides of the USB plug, but not the connections on the end - the most important part of the drive! They undoubtedly chose this course, like many other manufacturers, to eliminate the problem of lost flash drive caps. A capless system would be fine, if the connections of the USB Plug were afforded some degree of protection.

While it may sound like I've blasted the PNY 64GB Flash Drive, it still has its place. However, the short comings of the new design - no LED activity indicator, cheaper case, and only partial protection for the USB Plug do affect its versatility & reliability; especially if it's used as a daily worker.

A decent Case Logic case, would be a good & highly recommended compliment, to the transport & integrity of this flash drive. At the very least, it would give the USB Plug some much needed protection, while prolonging the life of the flash drive.

5Excellent
By Greg J. Lovern
I picked this up at Fry's after my Lexar JumpDrive TwistTurn's hinges broke. Previously, I had used a couple generations of SanDisk Cruzers until they recently changed to a dumb design and became very slow.

What I've always wanted in a USB flashdrive is a good, strong keyring attachment and a non-removable cap. This PNY Attache has both.

It's also more compact than the Lexar JumpDrive TwistTurn and the SanDisk Cruzer.

It doesn't have a LED to light up when it's connected, but that's fine with me.

The sliding cap can be a bit stubborn; avoid it if you have weak hands or arthritis.

One reviewer here noted that the cap doesn't protect it from dust etc. falling into the plug. True enough, but that's not the point. The point is to prevent the end of the plug from being BENT. And it's good for that. The SanDisk Cruzer is the same way, and I never had any trouble with any pocket dust that got into the plug. If any does get in you can just blow it out.

UPDATE:

I've noticed that if the computer goes to sleep and then wakes up, I have to remove and reinsert it; otherwise the computer just sits there and seems to wait for it to respond. I didn't have that problem with the SanDisk Cruzer or the Lexar JumpDrive TwistTurn. It's annoying but I can live with it.

1Bloody Useless
By Pitchy
Had the drive for about a week and now it's useless. The drive has went into a "write protect" mode and magically added about 20gb of phantom data that does not exist. I have 6 files on there and the largest one is 2.6gb. So there is no way I have 47gb in use, even though when I check the properties and I only have 9.1gb used. The reviews here don't talk about it, but if you google PNY WRITE PROTECT you will find tons and tons of people with the same issue. Best Buy reviews all talk about it.

I have two 32gb PNY drives that work great, but this one sucks. I have tried everything I can think of to correct this problem. I will most likely have to return it to either Amazon or PNY. Either way, this WRITE PROTECT problem seems very wide spread so I would look at other drives. Probably a reason why this 64gb drive is cheaper than most 32gb drives.

4Decent card at a great price, missing very little
By Accountability
Although the file system may prove confusing to many at first, this card is one of the closest things you can get to a mini-SSD (tiny non-moving hard drive) for at or under ~$100 (less on sale).

I decided to write a review here because many other reviews didn't mention a few critical pieces of information.

First and foremost, this card does support alternate file systems. Out of the box, if you don't have at least Windows XP SP1 (with update KB955704) on your PC, OSX 10.6.4 on your mac, and the "SDXC" logo on your camera or device, this card may not be recognized properly in its native exFAT filesystem, and your various computers and devices may not be able to format it in a way that is compatible with your other devices. If you format the card with NTFS, it will work on older Windows systems (and UNIX-based machines with ntfs-3G or FUSE-ntfs). If you format it with FAT32, however, it will work on almost every device I tested, even those which claim to support the SDHC (32GB max) standard. This is because there are basically no physical differences between older SDHC cards and these newer SDXC cards except for their capacity. Additionally, this means if you format the card with FAT32 on a compatible computer, you can use it in almost every camera, computer, or device that supports 4GB cards. That's right, when formatted to FAT32, I've tested it in a couple of devices that advertised a maximum capacity support of only 4GB, and it still played well with all the other old devices too!

Compatibility aside, the speed of the card deserves note. All cards are internally printed on different wafers of NAND (that's the actual flash memory inside these chips), so results may differ slightly especially in terms of small cluster random writes, but with my system and reader I have benchmarked sustained write performance of 16.4MB/sec and sustained read performance of 42.6MB/sec. If the "class" system were to be expanded, this card would therefore be closer to a "Class 16 card" in write performance and/or over a "Class 42 card" in read performance. I tested this on the built-in card reader in my 2011 Dell laptop, so if anything, these figures are conservative and you may experience higher transfer speeds on a dedicated USB 3 SDXC reader.

I've used many Kingston products over the years, and most if not all have been virtually problem-free. This card lives up to the trend. (Yes, I've used a lot of SD cards!) For better or for worse, this means I cannot comment on the warranty, since I've never once had to use it.

The only reason for deducting one star is lack of UHS-1 controller support at this capacity and price, so it does not explicitly take advantage of the faster 104MB/sec bus speed or 1.8V low-power operation mode. It is not consistently the cheapest card in this capacity, nor is it the fastest or "lowest power" to use (yes, this may become important when your whole device operates in the mW range). For most, the distinction is next to nil, but I found it worth mentioning regardless. In sum, although it strikes an excellent balance, it is still a tiny bit lacking in other technical regards.

3Worked for awhile, then quit
By Amazon Customer
I bought this card in March of 2013. By May, the card would not function in my tablet. After reformatting it, it still resulted in continuous I/O errors. Unfortunately Amazon would not return this item because it was out of their 30 day window. Buyer Beware!
A followup: I was initially frustrated, but Kingston's lifetime warranty was honored very professionally by the Kingston company. I mailed them back my card and they sent a new one that has worked perfectly thus far. Therefore I am raising my rating to 3 stars. If it works for an extended length of time, I will raise it again because of the excellent customer service.

3Slower than expected
By AdamDZ
Rather slow for a Class 10 card. It writes 11MB/s and reads 22MB/s. My other card is 64GB SanDisk, also Class 10, and it writes 20MB/s and reads 45MB/s. I bought this to have some extra storage in my MacBook Air and it's a perplexing choice: less storage, but quicker, or more storage but slower. BTW, test results were the same on the Air and my Dell Latitude regardless of the filesystem.

5Fast Flashdisk Performance
By OldAndSmart
Ordered the 32G version. Ran a benchmark on it, and it is able to write at 15 MB/sec and read at 30 MB/sec for large files (posted screenshot). Very fast! The picture makes is look as though the stick is slightly curved, which it is not. Also, the picture conveys a higher quality finish than is actually on the unit. But it does have a very slight "heft" that feels like quality. I like the design which I hope will be a long lasting and ever available keychain dongle. Since it is so new I can't speak to its reliability in this use.

5Fast, durable and solid USB storage
By BranThomps
I ordered the 64 gig version of the Silicon Power Firma ZN flash drive and the similar, but smaller Kingston Data Traveller USB drive. The Silicon Power flash drive is very nice. It fits on my keychain very nicely with a key hole that is perfectly sized to allow wiggle room when using the flash drive with keys still attached. The Kingston flash drive is much smaller, but that makes it hard to handle and it doesn't have any room for your key chain loop to wiggle when you use it still connected. The Silicon Power drive is fast, works great on my Mac and PC as I have it formatted with the factory FAT filesystem. It has held up well for the last three months on my keychain and shows virtually no signs of rubbing against my other keys. I agree with another reviewer who mentioned that the photos make it look like it is curved. It is absolutely flat and actually tapers where the loop is, which makes it fit on a keychain even better. I do find it AMAZING that I am able to carry around 64 gigs of storage on my keychain. Years ago that was a whole stack of hard drives.. many years ago it was unfathomable to have that much space, much less own it for $40. We are the Jetsons! What will my kids have access to???

53 reasons I selected Silver Gray 64gb
By John L Murphy
I read up on many flash drives at the 32-64gb levels. I found the 128gb ones did not seem to please enough discerning customers at Amazon. I opted for a smaller USB 64gb 2.0 one, yet the largest (to date) made by Silicon Power Firma at 64gb, for three reasons. If you want a metal one, ensure you check the Silver Gray option.

1) Sturdiness. It is tough metal and not plastic, so there's less to chip off or wear away. Obviously, the ring attaches to a keychain or lanyard.

2) Design. No cap to lose or slide to wear off the wrong way. Although I hate not having this covered up, it's recessed enough (one hopes) for the protection desired.

3) Price. This meets my needs and is competitive with other brands.

I plugged it in. It fits very firmly, with less wiggle room than a conventional design. Insert and remove it carefully. P.S. While my laptop would not (IE platform installed by my workplace) recognize the set-up, I simply opened up the drive as one would any USB device. I dragged files in and they transferred easily. This is a small size, a bit less in thickness and length than the USB type with a cap, so I recommend anchoring it to a keychain and keeping it off the other keys and metallic items to minimize scuffing or bending, but I'll reckon it's made to last.

1Large capacity, but slower than a turtle!
By Ravi
I have used a lot of flash drives, dating back to 4/8mb drives. I've received a lot of promotional drives free from various conventions, but I've yet to see a flash drive made out of material as cheap as the Glide drives are.

The transfer speed is just plain simple horrible. I transferred 500mb of data, various sized files and I got an average of 4.1MBps transfer speed. So to fill the drive, it'll take 4+ hours. In this day an age, having a write speed of 4MBps is just not acceptable. No matter how low the price point of a drive this size is, a low write speed is not acceptable. I got this fairly cheap for the storage size and I don't expect the memory chip on-board to last long. Sadly I no longer have the packaging to return it to the store.

I've owned plenty of SanDisk products (SD Card, CF Card, USB Drives) over the years, and I've seen the decline in quality over the years. Wonder where it goes from here!

3Huge Capacity - a bit slow...
By Deniz Sevki Kayabay
I've got several USB flash drives, both from Corsair & Sandisk with considerably large capacities. I've bought the Sandisk Cruiser 128Gb for the back-up of essential files. Though the drive has a large capacity, the speed of the drive is not satisfactory, as 6 to 7 Mb/seconds write mode and 22.5 Mb/seconds read mode. The fastest flash drive I've ever used was a Corsair Flash Voyager Mini 32Gb, which exceeds 20 Mb/second write & 35Mb/seconds read capacities. So if you're looking for a huge flash drive but no performance Sandisk Cruiser 128Gb might be the only choice. But if you need some performance & a speedy drive I'll propose Corsair Flash Voyager Mini 32Gb. ( The first test result of the Sandisk Cruiser: 12Gb ( 12,500 files ) transfer from a high end computer will last about an hour ! )

5It is like Star Trek to me!
By David Wilson
I am 70 years old and personal computers weren't even invented til I was in my 30s. So it is all still like magic to me. However, these little flash drives are unbelievable. I have four in a little tin box that once carried breath mints--and they carry over 500 GB of movies. Even Spock wouldn't have belieived it.

5This Sandisk 'class-4' micro-SDHC card is faster than a PNY 'class-10'
By NLee the Engineer
I purchased a SanDisk 32 GB microSDHC Flash Memory Card SDSDQM-032G nearly two months ago, for use in my VIZIO 8-Inch Tablet VTAB1008. At the same time, I also purchased a higher-priced PNY 32 GB microSDHC Card (P-SDU32G10-EFS2) which is supposed to be a 'class-10'. My benchmark results, however, show that the Sandisk class-4 card is actually faster - most of the time.

I used two sets of benchmark programs. One is called 'Flash Memory Toolkit v2.0', which measures the random read/write speed of files between 1MB and 15MB. The other one is called 'H2testw v1.4', which measures the sequential read/write speed using 1GB files. Here are my results: (see my uploaded charts in 'Customer Images' section for details)

- For smaller files (1-5MB), the Sandisk class-4 card gives an amazing write speed of 15-17MB/s, while the PNY 'class-10' card can only get 1-6MB/s

- For larger files (10-15MB), the Sandisk and PNY cards are about equal at around 8MB/s for write

- For huge files (1GB), the PNY did better at 9.5MB/S, while the Sandisk dropped to 5.5MB/s

- The read speeds of both cards are equally high at around 18MB/S (this number may be limited by the maximum speed of my card reader used)

What the above shows is that: When used in a typical digital camera (with file size 3-5MB), this Sandisk 'class-4' card is at least twice as fast as the PNY so-called 'class-10' card. But when used in a HD video camera (sequential writing of huge file), then the PNY card should perform better.

For a card to be marketed as a 'class-10', it must maintain a MINIMUM write speed of 10MB/s. So by this definition, the PNY card does not qualify since it cannot even achieve a MAXIMUM write speed of 10MB/s. This Sandisk card, on the other hand, exceeds the requirement of 'class-4' by a huge margin.

Sandisk seems to be the only flash memeory manufacturer that still gives honest, conservative speed class ratings. Any other manufacturers would have labeled this card a 'class-6' or even higher. As a matter of principle, I rather give my money to a company that promises less but delivers more, instead of to others that do the opposite. At the present cost of about 1 buck per GB, this is an unbeatable deal!

[Aside]
The capacity of this card, as reported by my computer, is only 29.7GB. Note that this is actually normal, because compter people define one 'Giga' as '2 to the power 30', which is 7.4% greater than 1 billion. So 29.7GB comes to just about 32 billion bytes, which is '32GB' according to marketing people.

[Update Dec 3, 2011]
I re-tested the two cards above, using the CrystalDiskMark v3.01. The results are consistent with my previous finding. See my newly uploaded charts in 'Customer Images' for details.

[Update Nov 19, 2013]
The Sandisk card is still working fine after two years in my tablet. It should be noted that I have purchased dozens of CF/SD/microSD cards over the past decade, and only experienced ONE card failure (which was caused by an incompatable card reader). So I'm probably just more careful in handling memory cards. For example, I always make sure to discharge myself electrically before touching a card to avoid ESD zap, and use "Safely Eject USB Device" command to remove a card.

5Great price on a genuine product
By Doug
This is a great price for a 32GB SanDisk micro sdhc card. Don't let the 10 people who gave this a 1 star rating scare you, this is a great price for a good product. Anyone who works with computers or technology in general knows that you will occassionally have a device that just fails. I work a computer helpdesk and see it with hard drives all the time, it happens. That's why any good manufacturer warrants their product, so if you have a failure like this, you get a new one. These types of failures are unavoidable.

This is a geniun SanDisk product, sold by Amazon.com and not some third party seller. Buy with confidence.

1A deal, but, if given the option CHOOSE (RETAIL PACKAGING) OR YOU WILL RECIEVE A COUNTERFEIT ITEM. No joke.
By Benjamin Anderson
***
Update: As far as I can tell, there is no more non-retail packaging option on this product... hopefully they realized what was going on and changed it. But if the option is there again, make sure the item you add to your cart is (retail).
***

I meant to order "retail" packaging the first time, but I rushed and I wasn't careful enough. I got the crappy "hassle-free packaging" one instead. Huge mistake. However, I WAS NOT AWARE THAT AMAZON INTENDS FOR THIS TO HAPPEN THE MAJORITY OF THE TIME BECAUSE THEY ARE ACTUALLY SELLING YOU A COMPLETELY DIFFERENT PRODUCT THAT IS MUCH, MUCH CHEAPER FOR THEM TO MAKE. Although, I assume that's part of how Amazon offers low prices.

The amazon page for this item secretly contains 2 items:
SDSDQ-032G-AFFP (Default item. Counterfeit. Poor chances of receiving a card that's not a knock-off/counterfeit/lesser-quality item, OR an item that was previously returned/refurbished/slightly-damaged-but-good-enough-for-hassle-free-packaging.)
SDSDQM-032G-B35 (Retail item. Legitimate. Excellent chances of receiving a new, legitimate SD card.)

Amazon (immorally) tries to get as many people to buy the non-retail one as possible. For example:
#1 Your browser automatically refreshes the web-page to this item whenever you do ANYTHING other than clicking "Add To Cart", after you have selected "Retail". I confirmed this after getting a crappy card.
#2 When you click on *ANY* link to the current SanDisk 32GB class 4, it'll take you to the COUNTERFIET one (SDSDQ-032G-AFFP) no matter if you clicked on the Retail one (SDSDQM-032G-B35) or not!!!
#3 The reviews for the two items are combined.
#4 When you select "Retail", the only picture that changes is one of the SD cards changes to a red retail packaging one. It's extremely subtle on purpose, and I don't even think that's real retail packaging, but whatever.
#5 Search the 1/5 and 2/5 star reviews. Note how they are mostly people who bought the counterfiet one (SDSDQ-032G-AFFP)? And people who bought the retail one (SDSDQM-032G-B35) are more likely to give a good review, with a higher read & write speed??

It's obvious... Do not buy SanDisk cards that have 'Bulk' attached to the name, or 'Frustration-Free', or anything else other than "Retail"!

Also, here's a short guide for repartitioning/reformatting with GParted, if you were unlucky enough to get a lesser-quality card, or are having issues with one (I'm sure there's Windows software too, just Google it):
Short version:
1. Insert your SD card into a microSDHC USB adapter (commonly comes with SD cards, also on Amazon for a few bucks).
2. Plug the adapter into your computer and make sure the SD card is recognized.
3. Download and Run: GParted. (Free, comes with Partition Magic, you may need to boot into it).
4. Select the drive in GParted, and click "create new partition table" in MSDOS (erases drive).
5. Re-partition the drive in whatever filesystem your device requires (look it up, usually FAT32).
6. The size of the partition can be your entire card, except the first 500MB. Make sure that you leave about 500MB of unallocated/free space BEFORE the rest of the partition. You'll end up with a 28.5GB card instead of a 29GB card, but your speeds, stability, and compatibility GREATLY increases. Note: This is also true with many other flash drives and external storage.

Out of the box, if you don't have at least Windows XP SP1 (with update KB955704) on your PC, OSX 10.6.4 on your mac, and the "SDXC" logo on your camera or device, this card may not be recognized properly in its native exFAT filesystem, and your various computers and devices may not be able to format it in a way that is compatible with your other devices. If you format the card with NTFS, it will work on older Windows systems (and UNIX-based machines with ntfs-3G or FUSE-ntfs). If you format it with FAT32, however, it will work on almost every device I tested, even those which claim to support the SDHC (32GB max) standard. This is because there are basically no physical differences between older SDHC cards and these newer SDXC cards except for their capacity. Additionally, this means if you format the card with FAT32 on a compatible computer, you can use it in almost every camera, computer, or device that supports 4GB cards. That's right, when formatted to FAT32, I've tested it in a couple of devices that advertised a maximum capacity support of only 4GB, and it still played well with all the other old devices too!

Compatibility aside, the speed of the card deserves note. All cards are internally printed on different wafers of NAND (that's the actual flash memory inside these chips), so results may differ slightly especially in terms of small cluster random writes, but with my system and reader I have benchmarked sustained write performance of 16.4MB/sec and sustained read performance of 42.6MB/sec. If the "class" system were to be expanded, this card would therefore be closer to a "Class 16 card" in write performance and/or over a "Class 42 card" in read performance. I tested this on the built-in card reader in my 2011 Dell laptop, so if anything, these figures are conservative and you may experience higher transfer speeds on a dedicated USB 3 SDXC reader.

I've used many Kingston products over the years, and most if not all have been virtually problem-free. This card lives up to the trend. (Yes, I've used a lot of SD cards!) For better or for worse, this means I cannot comment on the warranty, since I've never once had to use it.

The only reason for deducting one star is lack of UHS-1 controller support at this capacity and price, so it does not explicitly take advantage of the faster 104MB/sec bus speed or 1.8V low-power operation mode. It is not consistently the cheapest card in this capacity, nor is it the fastest or "lowest power" to use (yes, this may become important when your whole device operates in the mW range). For most, the distinction is next to nil, but I found it worth mentioning regardless. In sum, although it strikes an excellent balance, it is still a tiny bit lacking in other technical regards.

3Worked for awhile, then quit
By Amazon Customer
I bought this card in March of 2013. By May, the card would not function in my tablet. After reformatting it, it still resulted in continuous I/O errors. Unfortunately Amazon would not return this item because it was out of their 30 day window. Buyer Beware!
A followup: I was initially frustrated, but Kingston's lifetime warranty was honored very professionally by the Kingston company. I mailed them back my card and they sent a new one that has worked perfectly thus far. Therefore I am raising my rating to 3 stars. If it works for an extended length of time, I will raise it again because of the excellent customer service.

3Slower than expected
By AdamDZ
Rather slow for a Class 10 card. It writes 11MB/s and reads 22MB/s. My other card is 64GB SanDisk, also Class 10, and it writes 20MB/s and reads 45MB/s. I bought this to have some extra storage in my MacBook Air and it's a perplexing choice: less storage, but quicker, or more storage but slower. BTW, test results were the same on the Air and my Dell Latitude regardless of the filesystem.

5Great read , but mediocre write
By Sushi Roll
I purchased the 32gb version . Its spacious and has great read speeds but the write speed is mediocre compared to my AmazonBasics 16gb microsd that gets 24MBps read and 22MBps write
Using a Transcend USB 3.0 card reader I get
On ATTO 45MBps read ; 14 MBps write
and on CrystalMark 45MBps ; 13 MBps write

2I am dispointed
By Wei
I have this Sandisk Ultra 32GB class 10 30MB/s SD card. I have to say I am totally dispointed. It's SLOOOW. I did two speed tests.

First test was performed on a computer using a software named "CrystalDiskMark". I ran the test with 3 different SD cards on the same pc with same equipments and same setting.
Results:
Sandisk Ultra 32GB class 10 30MB/s SD card, Read 19.93MB/s and write 11.99MB/s.
Sandisk Extreme III 4GB class 6 SD (5 year old card), Read 18.67MB/s and write 16.67MB/s.
Transcend 16GB class 10 SD (8 month old), Read 18.74MB and write 17.25MB.

Second test was performed on Canon T3i DSLR with the same 3 SD cards tested above. In this test I set my DSLR to burst mode and TV mode with 1/50 sec. Within 30 seconds interval, I want to see how many pictures in RAW format my camera can shoot.
Results:
Sandisk Ultra 32GB class 10 30MB/s, 24 shots.
Sandisk Extreme III 4GB class 6, 34 shots
Transcend 16GB class 10, 33 shots.

Conclusion:
As you can see this Sandisk Ultra card havs higher read speed. I belived my card reader is max out at 20MB/s. that's why it show 19.9MB/s read speed. However for a digital camera and camcorder, the write speed is more important than the read speed. Both tests clearly show that the Sandisk Ultra only meets class 10 rating but far behind the other two cards. The cheaper Transcend card can outperform this ultra card easily in write speed.

5Excellent card, but misleading.
By Roger
I am giving this memory card a 5 star review because it is sufficient for virtually all HD video needs. I can record at 1080p @ 30 fps on my Canon T3i with absolutely no issues, however the speeds I received when benchmarking were nowhere near 30 mbps. For sequential read I got 18.70 MB/S and for write I got 11.75 MB/S. Now I know its advertised as up to 30 mbps reads. But I feel it may be misleading. However since it fulfills all my demands perfectly I will give it 5 stars.

5The Fast and the Spacious
By Avid Reviewer
The Kingston 8 GB microSDHC Card works flawlessly with all my memory card readers: Kingston Mobilite, Kingston microSD Card Reader, and SD Card Reader. Windows (XP) has no trouble recognizing it as a removable drive.

- Device Compatibility
Using a microSDHC to MS PRO Duo Adapter, I am able to use the Kingston 8GB microSD in my Sony Cybershot DSC-W170 Camera -- it works like a charm; the camera has no trouble capturing pictures and videos (at a frame frate of 30 fps and a resolution of 640 x 480 pixels). All of my devices, such as my Garmin nüvi 360 and my HP iPAQ 111, are able to recognize the full capacity of the SD card.

- microSDHC Format
microSD cards of 4GB or larger are known more specifically as microSDHC cards. This 8GB Kingston card is therefore a microSDHC card. Beware that some older devices are NOT compatible with the microSDHC format. Such devices will only work with microSD cards with capacities of 2GB (such as this Kingston 2GB microSD card) or less.

(The technical specification for the SDHC/microSDHC format supports capacities ranging from 4GB - 32 GB. microSDHC cards of 16GB, such as this Kingston 16GB microSDHC card, is the largest capacity available as of this writing.)

- Class 4 Speed
This SD card is rated class 4 (data transfer rate: 4 MByte/sec, or 32 mbps) - sufficiently fast for the majority of electronics. A decidedly small number of electronics, most notably some camcorders and high-end cameras, require a class 6 SD card (the fastest transfer rate as of this writing). Transcend makes one that's rated class 6.

- Frustration-Free Packaging
Kudos to Amazon for their Frustration-Free Packaging efforts in using only recyclable packaging materials and in keeping the amount of packaging used to a bare minimum. As a giant in the e-tailing industry, Amazon's move will no doubt serve as an impetus for getting the rest of the e-tailers to follow suit!

---
The Kingston memory card is compatible with devices that support the microSDHC format. It is a fast (class 4) memory card with plenty of storage. Definitely recommended if the specs meet your needs!

5Works for BlackBerry 8310
By M. Krasilinec
I didn't see any reviews for this product, so I wanted to let you know that the 8GB (7.4GB usable) works on my BlackBerry 8310.

Interestingly, although the BB showed 8GB with the new card, I only saw 4GB (3.2 or 3.4GB usable) when I first connected to my laptop and the computer asked to format the card when I enabled Mass Storage Mode (I used this mode to drag and drop into the BB). I could only see 4GB on my work computer as well.

However, after standalone reformatting the card (to FAT32) on my friends Compaq both of my computers (and phone) now properly see it as an 8GB card. My computer and phone information is below.

laptop: Win XP Pro w/ 4.2.2.12 BB Desktop Manager
work computer: BB desktop manager 4.6.0.12 with win2k pro
phone: curve 8310 with firmware: v4.2.2.170 and AT&T as provider

I'm looking forward to using the expanded storage!

1Do Not Buy This Product from RW Digital
By kristopolous
RW Digital is selling fakes. They are conning you. My module only wrote 2GB or so and then crapped out.

Kingston Inc said this was a counterfeit and will not support the product. RW Digital has not returned my inquiries.

DO NOT BUY THIS PRODUCT FROM RW DIGITAL.

5Fast Flashdisk Performance
By OldAndSmart
Ordered the 32G version. Ran a benchmark on it, and it is able to write at 15 MB/sec and read at 30 MB/sec for large files (posted screenshot). Very fast! The picture makes is look as though the stick is slightly curved, which it is not. Also, the picture conveys a higher quality finish than is actually on the unit. But it does have a very slight "heft" that feels like quality. I like the design which I hope will be a long lasting and ever available keychain dongle. Since it is so new I can't speak to its reliability in this use.

5Fast, durable and solid USB storage
By BranThomps
I ordered the 64 gig version of the Silicon Power Firma ZN flash drive and the similar, but smaller Kingston Data Traveller USB drive. The Silicon Power flash drive is very nice. It fits on my keychain very nicely with a key hole that is perfectly sized to allow wiggle room when using the flash drive with keys still attached. The Kingston flash drive is much smaller, but that makes it hard to handle and it doesn't have any room for your key chain loop to wiggle when you use it still connected. The Silicon Power drive is fast, works great on my Mac and PC as I have it formatted with the factory FAT filesystem. It has held up well for the last three months on my keychain and shows virtually no signs of rubbing against my other keys. I agree with another reviewer who mentioned that the photos make it look like it is curved. It is absolutely flat and actually tapers where the loop is, which makes it fit on a keychain even better. I do find it AMAZING that I am able to carry around 64 gigs of storage on my keychain. Years ago that was a whole stack of hard drives.. many years ago it was unfathomable to have that much space, much less own it for $40. We are the Jetsons! What will my kids have access to???

53 reasons I selected Silver Gray 64gb
By John L Murphy
I read up on many flash drives at the 32-64gb levels. I found the 128gb ones did not seem to please enough discerning customers at Amazon. I opted for a smaller USB 64gb 2.0 one, yet the largest (to date) made by Silicon Power Firma at 64gb, for three reasons. If you want a metal one, ensure you check the Silver Gray option.

1) Sturdiness. It is tough metal and not plastic, so there's less to chip off or wear away. Obviously, the ring attaches to a keychain or lanyard.

2) Design. No cap to lose or slide to wear off the wrong way. Although I hate not having this covered up, it's recessed enough (one hopes) for the protection desired.

3) Price. This meets my needs and is competitive with other brands.

I plugged it in. It fits very firmly, with less wiggle room than a conventional design. Insert and remove it carefully. P.S. While my laptop would not (IE platform installed by my workplace) recognize the set-up, I simply opened up the drive as one would any USB device. I dragged files in and they transferred easily. This is a small size, a bit less in thickness and length than the USB type with a cap, so I recommend anchoring it to a keychain and keeping it off the other keys and metallic items to minimize scuffing or bending, but I'll reckon it's made to last.
