NEFFRY
I bought this a little under a year ago to use with my laptop. Worked just as advertised for much of that time until it stopped letting me write or delete stuff from it (could read just fine). I couldn't even format it. So it kinda just sat there for a while. After trying to format it a number of different ways, I finally contacted sandisk, and they said they will send me a replacement free of charge. I would have maybe given this a lower rating, but the customer service from sandisk made up for the faulty card. I am just glad it fell under a warranty period (I think). Had the card not failed, I would have given five stars. If sandisk wouldn't replace it, would have given one star. Hopefully the latter doesn't happen to you
