Because I have this ever bought for my equipment. These films are simply outstanding. Cheap films are usually very thin and can not be applied correctly and without bubbles. This film is easy to apply and very clean. The surface should be very clean but already, even a speck of dust is like a mountain and is visible. Cheap films can not compete with this film (once tried, never again), so I am also very specifically for films of FoliX and have always made the right choice. As always, a very good film.
