Got this card in early January for my Samsung Tab2 10.1 tablet.  Within a couple of weeks, it was loading music files incorrectly onto the card.  I did not know what was wrong, but finally thought I would format card again to see if that would correct the problem.  Card would not quick format or format slowly.  As always, Amazon is taking care of the problem and I will have replacement card within 24 hours!  Hope the replacement is more reliable.  I am just writing it off as a fluke, as I have never had a problem with a SanDisk product in the past.2/14/13:  When I called Amazon they replaced it - to my door - within 24 hours!  Replacement works fine.  Now that is GREAT service!
