I've ordered this film, because I want to protect the screen of my iPhone.
There are Luckily 2 films, the first just wanted to not fully invest in the display. The center put on without any problems, but remained around the entire display an approximately 2mm thin strip, on which the film is not completely docked at the display. My attempts to fix the problem were unsuccessful, so I picked up the second film.
The second film is read and holds tight, completely without any bubbles, booze, or anything on the display without major problems.
This bulletproof glass films are not bad and if both were stuck without a problem on the display, they would have been hit hardly for the price, but I can only a working film and there are better deals, here on Amazon.
Perhaps my first film was a production error, or I have made myself too stupid - that's why there are only 4 stars.
