I was, as always with protectors, very skeptical when I ordered this for my iPhone 6, but it was unnecessary. The provision has never been so easy. I have kept exactly to the instructions, and there were already no longer air bubbles under the film before I have this still pressed. They moved as if by itself toward the edge, probably due to the more stable version of the film. At the top you can see, unfortunately, exactly, that a film is attached, since the iPhone's bevelled there. There they would therefore may be one millimeter shorter. Otherwise, I am very satisfied.
