Quality has a price. Do not rely on a low price, which obviously hiding something. In my case, the card was not working. She showed a capacity of 64GB well, you could "copy" 64GB, copies were made without "error" but once completed, the map did not contain the copied files. Only the first GB (I have not measured) contained something. The rest was empty. In short, go your way. This card must be a rebus of series production but does not hold a charge. The've returned to the seller. Wait a refund but I left still 12 postage and back. I repeat: no miracles in this world. Quality has a price too low for RAM often hide the stew.
