*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.

Micro SD Card: Good / Reader: Not so much

As advertized
The MicroSD card worked in my phone without any issue. The card reader is a little flaky, though. But for the price, it is a good deal.

16GB SDHC card ok, readers not
This package included both the 16GB class 4 microSDHC card from Sandisk and a microSDHC reader. I ordered two of these sets. Read more

Works, but wish there had been a non-bundled option to match this...
I bought this because it was the cheapest item that suited my needs, but wish I could have gotten just the card - I didn't need the rest.
