The film on a cell phone screen without air bubbles, without fingerprints (which arise when you subtract the film - and somewhere you have to adjust the foil yes - or?) On auszukleben's first time and without dust is just not possible. To start up and accurately reach first the corners and cut-outs, then the aufzustreifen Falie smooth with a credit card took me four tries and a slightly sloping result. The film we must not raise or pull back a bit, because then it is no longer sticky. The fifth attempt I have then just with a little scotch fixed (which certainly can not be the point of it). Six delivered films I now have only a - I'm not sure if I should try again, then the last one is still "stuck"?
