Don't buy these!!!!
I saw these on Ebay a month or so ago, placed a bid and won it for around $32. The card came in the mail two weeks later, but it was complete rubbish - only about 2GB of the card was usable, although the computer recognized it as a 32GB card. Tried to move all my music at least 6 times, but no good - most of the files were corrupted and didn't work. I contacted the seller, he immediately gave me a refund without asking for me to ship it back, and for that I left him positive feedback, but I will never buy anything from him (grandtechdigital) again.
So yes, bottom line: if it's sounds too good to be true, then it probably is. I went for the plunge just because $32 was cheap and I could get a refund if I wanted to. However, it sounds like some of you weren't as lucky as I was.
