The films themselves are excellent! Sticking really surprisingly easy, I had quite a lot worse, in which the bonding was pure torture. It caused little bubbles here, which can push out again immediately and accurately, the film is also.
The only where you have to watch it: peel off the second protective films on the tab, after gluing on your mobile phone, the first time the entire film is again gone off with me, because I have not respected it. If one solves somewhat careful you have any problems :)
Overall a really good product for less money, just in the purpose of applying and fast since.
