Easy to fit, I managed to mine the first time! I first cleaned the screen with a liquid screen / glass, wiped the moisture with a paper handkerchief and finished removing dust with a microfiber cloth for glasses. The film is semi rigid, the easier it is to place the beginning of the film as shown, but then hold it vertically above the screen and place it on the surface gradually oting the backing sheet. The film is substantially smaller than the tablet, leaving a small margin immaterial to use. The movie does not seem to change the sensitivity of the screen or its brightness. There is a little less glare on the film than bare tablet, but it's not a dull film. There remains the question of its strength over time, but even if a film is damaged I still have always 5 in the lot ...
