I made the mistake of buying a supposed 64gig card on Ebay and found that it was fake. So, I decided to purposely buy a retail packaged SandDisk card directly from Amazon. The card is great, I reformatted it to fat32 for use with my Sansa clipzip and Hisoundaudio Studio V 3rd Anniversary. I have not had any problems with the card, works as advertised and the transfer speeds are great when loading files onto the card.
