I have to say never again raise films ... This glass let himself so easily raise that I will never again order me films. Use window because of dust dispersion, supplied lens cleaning ink, tighten with supplied microfiber cloth, with included stickers (yes, that's all !! with it) remove the last specks of dust, put oriented film, press shortly and the glass takes place as if by a vacuum itself ans display. Two weeks ago on the phone, yet can not see any scratches (extremely hard). Decreased streaking through special coating, I can confirm.
