I bought this card and it worked OK, at first. After about three weeks I noticed that some images were not showing up, a week later it began to loose everything. My Note 2 was failing to recognize it, inserted into the adapter and my comp could see it but not read all the files. Multiple formats by either the comp or Note 2 did not fix the problem, even tried some tools that I used for my DSLR, still no-go.This could just be a batch problem as the card looks legit and was fast in the beginning.
