I am fully satisfied with the protective film. She was easy to install and the appearance on the M8 I find also very classy. Of course, the brilliance of the display suffers a little, but in a matt film is part of the common sense that everything is a little darker. Fingerprints can not be seen, and I think the finger glides easily across the screen. The fit is 1A, as a previous speaker say, 1mm more or less have it may not be. My touch screen responds to be outstanding, the service is compromised, none case through the film. Who has never mounted a film, should already get the set of 4, because it is not so bad if he paint in the first does not work, after one or two films should also someone with 2 left hands, the film aligned bubbles and perfect have attached (the accompanying instructions show the procedure very well).
