I've only used the card a couple of times, actually I wanted to reformat it the first time after uploading all the files. It started giving me errors when I couldn't read multiple RAW files (5D MKIII) when importing into Lightroom. It was relative. Then after putting the camera back in, she couldn't recognize or format it. I am using a Kingston FCR-HS3 USB 3.0 reader which is recommended and works great with all other cards. I really wanted to like this card as it is an affordable alternative to expensive options. I can honestly say I've never had a bad memory card and use both CF and SD. I have several Transcend, SanDisk, Duracell and Lexar. I even have an old 8GB Blue Generic card that's about 5 years old. Nobody gave me a single problem. I'm an amateur photographer so I don't earn from it, but if I did I would be very skeptical about using the Komputer Bay card. I'll try to get a replacement but I'm not sure I can trust them now. Update: A replacement is on the way after trying to fix it with low-level formatting.
