The film fits perfectly and looks well made. The real difficulty is, as always in the exact application of the film on the display. These films have on the upper side and the underside, a protective film that protects the actual film again. Both are equipped with colored tabs and numbered. That makes it easy to understand then. So once rid the screen of grease and dust, then remove the cover sheet marked "1" and attach correctly on the display. One can equally pull the complete protective foil, or just starting on one side and only deduct part. In both cases, the danger is that small speck of dust settle on the back and then lead to blisters that no longer can be removed also, since the film no longer lies flat. One should perform the entire procedure in a dust-free room. But the bathroom is very good, especially when you advance a few minutes turning up the shower and the humidity makes the room practically dust-free. Did they still dust particles under the film, it usually makes little sense to withdraw the film once more, because the result is so only getting worse. Part of the bubbles you can with a credit card that I have with a microfiber cloth (the supplied cloth is not really sure) wrapped, smooth or at least push so far to the edge, that they no longer interfere. Then you can remove the cover sheet marked "2".
It is also clear that the application of such a film does not always work right away. Not for nothing one gets equal of five pieces. That does not matter. So a lot of films, even when you have to dispose of that be more than enough for the entire lifetime of the phone. When I was able to function with and without film is no difference between the use of the iPhone's notice. Overall a very good product with a very good price-performance ratio that is worth my 5 star.
