I bought this protector for my iPhone 4S and have it now 8 months in use! And I must say: Great! The application of the film was a bit tricky. Since I've never done before, I firstonce looked at me a couple of YouTube tutorials, so I afterwards no bubbles o. Ä. have. After some time she was on then until today. There are several films in the package, I have only 1 foil for the Front used and since the beginning, so 8 months. And it is still there! The film influences the display in any way, everything is clear and sharp to recognize, and it is of course a super scratch protection for the screen.
Strong buy recommendation, and unbeatable for the price!
