The Samsung memory card does not even have a protective cover. That is, if one performs several memory cards with them, woefully inadequate. Although these SDXC card has great performance, it will be the first and last memory card from Samsung. I use exclusively otherwise SanDisk memory cards of CF to microSDXC. With the quality of Samsung products including smartphone and SSD I Bich always satisfied. The SDXC card has been correctly identified in a Panasonic HC-X929 3 chip camcorder and seems to hold for the first test, the performance promises. The exclusive wrapping the card in retail blister is not a product defect in the legal sense, but not very happy customer. Because of cutbacks in the wrong place has been set. SanDisk makes it better, and we're talking about so relatively sensitive products, which should not lead to unprotected with.
