The instructions for attaching the film is very good and if you stick to it everyone gets this film on his mobile phone without dust and air bubbles. The fit is nearly perfect just on the edge, it might even be a touch more, but then it would be very difficult to bring the film well.
Despite the film I could find in the operation is no difference, the only thing that bothers me: you have to clean the screen frequently, because the fingerprints can be identified very quickly and looks very blurred with time there.
