I ordered a 64 Gig card, and the card received states it is a 64 Gig card, though it only hold 28 Gigs of Data! I got ripped off. I did not check it until after the 30 days had passed. But it appears to be some sort of scam. The card is clearly marked 64 gigs, and I have checked the card in two tablets, and two computers it is only a 32 Gig card.Edit: The company directed me to a tool to reformat this card and I was able to get close to my 64 gigs of data, though I do not like using third party tools. I have Windows, Mac and Linux systems and any of those OS's should have been able to format this card correctly. I will minus a star for having to use a third party tool. Otherwise these are great cards.
