This Micro Sd Card is fantastic. I had some fears that it would not work in my Samsung Galaxy II or my Motorolla Xoom Tablet. I ordered 2 cards and the work in both after a format from each respectively, both ssaid that they maxed out at 32 gig cards. I averaged 59.5 gigs of information after the format. I travel frequently and don't always have the opportunity to stream from a cloud so these cards fit perfectly for the time where I cant get a signal on an airplane or a hotel where I cant get a signal either. I use them for Mp3's, photos or video or whatever other storage that I need for documents.
