I bought this for my LG Optimus G Pro, to hold my 24 GB music collection - it works great.  It took a while to transfer all my music, but that can be expected.  Once I popped this into the phone and started us the music player, it found a cataloged all my music.  I don't like the latest default Android music player, but that's another story (and there are other music players you can download).
