The protective films are of good quality, the fact that I Magré "mistreats" often my laptop, protection is still in very good condition after 2 months!
The protection protects the screen very well because the cut perfectly adapted to the screen (not like some other movies also sold on Amazon that are more expensive but badly cut).
After, the downside is that it must be very careful in applying the film because as it is cut to the exact size of the screen, simply evil alligné a bit at first and must be repeated.
Personally I missed the first time, but I easily managed on 2nd try, and we saw 6 protections for that price, even if it misses more than 2 times, it is no big deal!
