It is to be sure to thoroughly clean the LCD surface before applying the film. It may remain on the surface no lint or dust particles. To this end, the delivery is a microfiber cloth at !! The film comes in three layers. First, the film on the (a sticker clearly marked) adhesive side must be removed. The film then gently streak on the LCD. If bubbles remain, then squeeze out carefully using a credit card and microfiber cloth. Finally, remove the second protective film on the top - finished. The film is hardly noticeable, the ambient light is, however, reflected significantly less. I'm very satisfied.
