All of mine are either SanDisk or Transcend - from 2 to 16 GB. Sometimes I reformat them two or three times a day - always in the camera. I've had a couple that have been washed and dried in my pants pocket and they still work fine. The only card I have ever had fail was a Lexar so I don't buy those anymore.
