The GGS screen protector has the advantage that this is a special glass, which is glued by its edges to the original display glass. The protective glass "floats" thus one millimeter on the actual display. This means that no bubbles can ever arise, as with directly applied plastic sheeting is sometimes the case.
The brilliance of the original displays, and the appearance of the camera is not affected in any way! The display continues to look like original and yet is protected from scratches before reliable! The protection can be easily removed again, the camera should have some variety in the bay the owner ...)
A must for any high-quality camera! But for every "cheap" camera suitable if the owners (like me) react extremely allergic to scratch the screen! ;)
