I bought this but the reader just doesn't work on Windows XP (old laptop), 7 (main PC) or 8 (Dell XPS 12 laptop). I've tried this with 6 different SD cards ranging from 2GB to 128GB and the reader doesn't show up in Device Manager (there is a 3 port hub) and doesn't read the period of the card. It's rubbish and 1 star the way it is. and the company doesn't even acknowledge that they sell the product! Avoid it!
