Yet very careful and patient, I had a hard time succeeding perfect pose! My screen was nevertheless devoid of any trace of dust and fat since the portable was new and still had its original protective film but I still took 5 attempts to get there. Jai yet followed the instructions in the manual indeed quite limited and more patterns are not very "talking" - but still javais bubbles or "points" and I find that lorsquon trying to readjust the film then this is still worse. But I do not know how or why the 5th test it was time :) - sest the film perfectly laid without bubbles, and no trace! My perseverance has not been in vain, and the result is impeccable, you really know that he there is a film on the screen because this is completely invisible and personally I think it does not spoil the brightness of the screen (which in any case can be adjusted) or sensitivity level of the touch screen. It is true that the cuts are not extremely precise, we must "cheat" a little on the top cut for the film does not stick to the docking button down, but it's really minimal and a good result is possible without redrawing the film. This purchase is very interesting compared to expensive films offered commercially. The pack is complete with old cloth and stickers provided to remove dust or manipulate the film without leaving fingerprints and if like me you are not very good (s) for your first attempts you still 6 films for 6 attempts!
