*EDIT*

The following review was written when there was only one seller of this product, and that seller is no longer selling this product so this review might not pertain to the current seller(s) now.

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

I'm pretty leery about buying memory cards online. If you don't know, it's possible to hack a smaller size card to make it appear that it's larger than it really is. So people will buy a cheap 1GB card, hack it to make it look like a 16GB card and then sell it for the going rate of a 16GB card. I can pretty much guarantee that any cheap card on eBay from China or Hong Kong will be a hacked card. The card works fine, as long as you never surpass the initial size of the card (in my example 1GB), but once you do, your data will be corrupt.

The only way to truly tell is to test the card. I used H2testw to test the card that I purchased. H2testw is freeware that you can find easily by doing a Google search. The results of my test were:

Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 5.49 MByte/s
Reading speed: 10.2 MByte/s
H2testw v1.4

No write or read errors, so the card is just as advertized, a 16GB card. Benchmark for a Class 4 is 4MBytes/s Write speed, so this card more than preforms at it's benchmark speed. Overall, I got a quality product at a quality price, and if anyone's in the market, I would recommend this card to them/

I purchased this Sandisk 16gb MicroSDHC Class 4 Card from Everything But Stromboli. It looks good. :)

I used Crystal Disk Mark 3.0.1 to test the speed. I was particularly interested in the Random Write 4KB (QD=32) for my Optimus T and Nook Color. I also ran H2testw to test the actual size of the memory card. Below are the results of the tests I ran.

works as advertised. Using in a Droid X, and it works great and is nice upgrade over the 2GB class 2 card it came with.
The USB card reader is a nice bonus, and it has come in handy with transferring files back and forth to an older PC that couldn't read SD cards directly. Just pop it in the USB port and away you go.

First, let me clarify... I did not purchase my card here through Amazon, therefore I cannot comment as to this seller and/or the legitimacy of the cards they are selling. I simply wanted to comment on this particular Sandisk product in general, and my experience with it.

I purchased my Sandisk 16 GB Micro SDHC Class 4 card from Costco, and spent an afternoon testing the card to verify the correct size and speed class. I bought from Costco because they have a wonderful return policy in case I wasn't completely happy with it.

Since I purchased the card to run in my HTC Evo, I did the testing on the phone with the card installed. The card tested genuine as a 16 GB card, and my write/read speeds were consistent for a class 4 card. Over several tests, I averaged a consistent write speed of around 4.5 MB/s and a consistent read speed of around 16 MB/s.

As is the case with my Evo, most smart phones on the market today (Evo, Incredible, Droid, etc) aren't designed by default to take advantage of higher speeds that higher class cards offer. You will probably not notice the benefits of anything over a class 4 card. However, if your phone is rooted then you do have some control over changing settings that might let you benefit from higher class cards. But even so, a good quality class 4 card should be more than enough to meet all your music, photo, and video needs. (I will take a class 4 Sansisk over a higher class card of any other brand for use in my phone any time)

But... Since we all have diffent phones, and since there are all sorts of different opinions on the subject when you read all the Micro SD card reviews, let me offer this simple advice...
