Simple review - this thing sucks!I guess someone bought this in bulk from China and now trying to get rid of it through amazon. Maybe this was $10/100 pieces wholesale.As for why it sucks. Plug it in - get's recognized, then after a few seconds it disappears. It disappears whether it's gathering dust or you're trying to get data from a memory card. My guess the chip overheats or some timing issue or bug in the firmware.
