With this protection (glass) iPhone does not lose its image quality. I tried several different movie and it's hard to come across a good, or they are matte, or they scratch at great speed V. This protection is thick enough but it plays its role of second skin. She did not see at first glance. The only downside is that the home button is recessed shallow ... And the little domed capsule (which is provided) is cute but it no longer allows the fingerprint recognition on the phone that allow it! I am still very satisfied ;-)
