Ultimately, I decided for this card from Samsung. I got very close to buy only the model with 32 GB version have me but then, given the attractive price equal to the 64GB decided. After inserting it was immediately recognized us was ready. The transfer of over 25GB of music and images worked quickly and without problems. Also the access to the files from the tablet works fine. This must match the long shelf life, it still remains, of course. Anyway, I'm totally satisfied with the card and the price-performance ratio. From me it's 5 star and a buy recommendation.
