Last June I bought this card, I was only pleased by the high speed and the competitive price. Two months later, the card refused their service. My photo wants to tackle with it not even more, some readers see anything. For me, that meant a loss of 12 GB on great holiday photos which I unfortunately could not previously secure. Returns and exchanges on Amazon ran smoothly and very quickly ... three weeks later, the new card also has a total failure ... and a renewed painful data loss. Who needs this card to take pictures you should back up very often! Or best yet bring rather just 4 small 4 GB cards.
