Works great on Samsung Galaxy Note 10.1, while the notice provides only a maximum of 32 GB (64-go with the built-in). I use it for 6 months and no pb met despite that "it is already 80% filled with music, video, books .... and day head works: MP3 reading and reading various doc. I had bought when purchasing a SanDisk 32GB that has not held 3 months: R / W errors repeatedly. In summary: 96 GB of storage (including 32 integrated) ...... What happiness !!!
