There are actually 2 screen protection sheets. One for the main one and another one for the small top one indicating DoF, etc..The protection screens are easy to apply, can be re-placed, no bubbles, perfect fit in size. You do not even notice them after applying and they do not alter the image quality of the screen. As they are hard, I cannot see how you would be able to damage the screen underneath unless stepping on it. So ideal protection. I highly recommand this product for EOS7D. I actually bought a similar products now for my old 400D.
