This is great!!  Works perfectly on the DROID Bionic!  After putting it in the phone for the first time I had to reformat the card.  The phone told me the card was damaged before reformatting.  Don't panic if you see that.  Just go in to your phone's settings, storage, SD Card, Unmount SD, and reformat that baby.  Now my phone has 80GB of total storage.  Less than that after formatting, but it's still a ton of space to put all of my music and movies.  Time to convert and load more movies now that I have 27GB left.
