I wanted a SD card reader for cheap, I was wrong. I'm me 3-4x served in one day and after that my SD card (Class 10) has finished HS. I can certify that this comes from the player himself but I emits very large soupsons to him, as on other cards, it sometimes has trouble reading ... (Class 10 also).
I will turn to a branded product even pay more and at least have the reliability that comes with it, because I did not want to burn all my cards for a 4th trick.
