Both films had me on a slight bend, so that was formed around this bend a beautiful air entrapment, which also can not prune. The first time, I still thought that perhaps had yet cheated hair under the foil. As the air pocket but formed exactly in the same place at the second attempt with the second film, I realized that both films are slightly bent at this point. In addition, the films are as good as not resistant to scratching. I have so far also experienced in any film. Disappointing is the fact that the actual film is not - as I am used to from almost all manufacturers, is surrounded by two support films, the first carrier film is removed during the installation process and the second, after all air bubbles have been pushed out. Both films have wandered into the garbage. As for the quality of films, has mumbi learn a lot in comparison with other manufacturers (egFoliX).
One thing makes mumbi but then good: The films conform very closely to the smartphone
Moral of the story: rather invest a bit more money in an ordinary film, as angry once and twice buy.
