SD cards of very poor quality. They seal them in bubble wrap and the flimsy cards break easily when you try to take them out of the packaging. But that's not the bad part. Only two of the 8 SD cards worked. I'm a computer engineer and I've tried 3 different readers on 2 different computers and in a camera. I tried to fix the broken cards with SD formatter but I couldn't even recognize the cards. In short, this is crap and should be avoided.
