Product line with my expectations, I took it to replace a 64GB Sandisk slamming my hands for the second time in 1 year (the Sandisk warranty service is increasingly litigious and slow ...) . I feel that the card is relatively fast, she cashed carefree large file transfers and rises very quickly on my smartphone (Samsung Galaxy). It remains to see the life of the thing in time, but for now I am very satisfied with the product which in addition is one of the best deals in terms of cost in its class.
