Stick-ons are not good either but it all depends how you carry the camera. I managed to break 2 on my 7D and chipped another one. And broke one on D800. So I replaced all of them with GGS III version. And got it for my new 5D3 too. The problem I think is that I carry both cameras close to my knees. There is a gap between the hard glass and back LCD. Because of lack of flexibility they break.
