Why Sony's camera card is more expensive than Kingston's?

Sony's SD card has a good compatibility with its own equipment. Kingston's really can't say anything. I used Kingston's 16G C1 card for my Sony camera. Every few days, the SD card can't be read, so I can only reformat the photos inside and recover them with easyrecover. That's enough. Let me throw away Sony's own card, so there is no such hidden danger. According to my own experience, there are no problems with other cards except Kingston's. Now I have three cards, one Sony 16G C1, one Sandisk 16G Extreme Speed and one Dongzhi 16G C1. Toshiba's quality is really good. By the way, Kingston has a lot of fakes. . .
