I see alot of pll on here saying that the m3 real made ther micro sd card go bad. I have had mine for a while now and I thowt it made my card go bad but it didnt. I got my boyfreind 1 and his did the same thing and he checked the card reader and it is junk. then he checked mine and it is junk. so be for you all junk your sd card check it in a difrent card reader. the 1 the m3 team send's you is crap. jest wunted to tell you all that I love the card thow .
