I have purchased SanDisk cards MANY years and I'm done! In the last couple of years the SD cards fall apart. I keep them all in a safe case free of bending and am always very careful with them. They chip, crack, start to open and one the other day just fell completly open. I have not had this happen with my Sony SD cards. SanDisk replaced a few for me over the last couple of years and today wrote and said they would not waranty this one. I'M DONE WITH SANDISK! Cheap quality, POOR service.
