Purchased after disappointing films DuraSec the membrane films are perfect! Poses with zero zero dust bubble 1 sudden I could not believe it! The films are slightly smaller than the screen E2 as reported by other reviewers but I think it's done on purpose to facilitate the installation, avoid the film overflows and eventually peel off. The film is completely transparent, does not alter the appearance of the high-quality screen and Liquid E2 is completely forgotten. I feel that the screen is exposed even with the film, no annoying reflection. Pure happiness!
