I purchased the 32GB version in November 2011 and had them in rational use. From one day to the next she suddenly took about 3 weeks ago problems, multiple devices (camera, computer) reported read error. I complaining the card that has 5 year warranty, then the Samsung customer service on the INet, we asked for photos of the front and back of the card and then told me a return authorization number. In normal Briefunschlag the card went back today, after about 10 days, I received a replacement. I had no appreciable data loss and am therefore satisfied with the smooth warranty processing. Nevertheless, I do not put it as a main card in my camera, a radical skepticism remained.
