I bought two SanDisk Extreme 80MB/s SDHC cards last January a 16GB and 8GB with my Olympus E-M1 camera and I have notice recently that pieces of the plastic is breaking off them, first it was on the top of the little metal strips and now the back is starting to break off on the left side where the slant is..

Today when I went to put the 8GB card into the card slot in the camera I noticed the front plastic is starting to separate from the back casing and its also starting to split below the lowest metal strip so I decided not to use it in case something else breaks off and it gets stuck in the camera to create more problems, searching on line I find many people have this same problem with SD cards breaking and not just the SanDisk brand.

What Brand of these cards do you use that don't give you any problems.
