The films are really very discreet: be aware that there is one !! And they no gene touch screen, m ^ mee with a stylus. For installation, there is a small guide in several languages (including French) and if we do as it says, you do it after a while. Hint: If the installation remains bubbles is that there are dust. Personally, I have removed just by using a piece of tape: dust glue on the tape more than the movie! And it's true that you can stick and unstick repeatedly. But beware: the best is sometimes the enemy of the good!
