I got asked for a free product trial offers the film. In the small envelope by Diplos were 2 'normal' screen protectors, and two more in a separate packaging with the inscription that they were slightly narrower cut for white phones. I have a white iPhone and I each tried a foil. First you have to clean the display dust free, then you can mount the film. The muster was relatively easy if you look at halts the Notice gradually withdraw the protective film and the same rework with a credit card. It goes almost without saying. Just at the corners I had to slightly rework. The films were both not fit 100%, in the narrow cut missing at one end so just 1 mm and in the "normal" control knob and the holes for speakers do not fit very well. The operability with foil is just as well and you can also see any film. She seems to look very robust. Pulling the film lies also very simple. Highly recommended because of easy mounting.
