I have received and applied the film yesterday and have therefore no long-term experience. This I submit to, however. The two films can be mounted very easily. Tools are not necessary. The small air bubble that I had after the application of the film for the big screen let out press / to emphasize easily. The films are minimally smaller than the display so that there is a gap of 0.5mm to 1mm bite the films. This I consider as an advantage, however, since you so already can put right the 1st test, the films.
