The quality of the film itself is fine, the application was for me a cramp, although not the first time I can muster a screen overlay. Air inclusions can happen quickly; that the real problem is actually extremely scarce cut, because if you do not really> 99.8% applied the film exactly, it no longer fits on the other side and there it stands out on the corner. Until it works, you need a lot of patience, good lighting and a very dust-free environment. Otherwise, there are no complaints.
