I ordered one of these http://www.centifly.com/en/Products/Products.asp?ID=31 off of ebay for about 8 bucks for my microsd. Got it in the mail today and plugged in my microsd and plugged it in the computer and was able to format my card. I then took it out and everytime I tried to use it again, it wouldn't work and was not being recognized at all by any of the computers I tried it in. I can send it back and get an exchange, but I have to pay for the two way shipping there and back. Should I just go to Best buy and pick up a reader for $15? Any suggestions? Anyone have any experience with one of these readers and now how to fix it?
