question:
I bought this card reader about six months ago. It was very easy to use, nice and fast to download but then suddenly quit working for no reason. I bought this because I figured it would have quality to last. I would not recommend buying this only because after a period of time you may risk going to use it as I did and it not working. I was very disappointed that it didn't last.
