    Decent speed for the price. The slider mechanism is simple and convenient. *Note that the newer models do NOT have an LED. The older models had an LED, so I'm taking away a star.

    I purchased a SanDisk USB 3.0 flash drive from Best Buy and was very happy with my purchase. I went back a couple of weeks later to purchase another one. This new one was horribly slow and, yes looking all over the package I found in very small print on the back that it was a USB 2.0 flash drive. Be careful, there are still USB 2.0 flash drives selling for almost the same price as USB 3.0 flash drives.
