Great film that keeps its promises. With a little practice everything goes wonderfully out of hand. In order to avoid dust inclusions I make the whole procedure in the bathroom - works mostly well. The fit of the film is very, very accurate. Sounds good at first, but may have problems preparing, if it is not 100% applied to the long sides of the smartphone ig parallel. There's hardly any air between the film edge and frame, the film is fast on top of the frame and therefore liable in this area is no longer on display -> Goofy. I have cut before the second attempt, the film again slightly narrower - so it went better. Small request: Quiet indent the film factory half a millimeter on all sides - then everything would be perfect! :)
