So I ordered two films. Once for my friend and once for me. The first film was full in the pants (a fun expensive). Because if you follow the instructions, then you can booze on the film not be avoided and thus has more bubbles. But if one makes the display clean and the film piecewise withdraws and they fixed simultaneously on the display, then it works and it also has no air bubbles. Almost none, at the corners, I still have a few, but do not bother reading. Otherwise, you can read with bubbles already, but these interfere significantly. So if you like written above does not follow the instructions, but the protective film only decreases when you mounted directly on the display. Again remove (slide just a bit remove and attach the free protective film on the screen. Slide a bit further and attach the display accordingly, continue to remove and replace immediately on the display, even with his hands. Then the bubbles go out automatically. NOT clean the display, remove foil completely and then fully put on display. It does not work!)
Hope it is somewhat understandable. But due to the difficult installation of me only 3 points since the manual is also bad, otherwise the film is ok.
