Lexar 16GB Class 10 UHS-1 600x 90MB/s High Speed Micro SDHC Memory Card with Reader
Very useful at the price, as this is the smallest USB 3.0 Reader available for Micro SD cards. It's cheaper to buy this and another ultra fast MicroSD card (upto 64GB), than buy the Lexar equivalent packaged product.
Recommending mainly for the reader (as you can't buy separately) but it's not a bad price if you are looking for a good very fast 16GB card. Backwards compatible with USB 2.0.
