The attachment is also quite easy due to the strength of the film, but I have it also can not stick without bubbles, but I think this is due to the lack of exercise and manual dexterity and not on the quality of the film.
The film is translucent and can, especially in the evening when the light is turned on, dimly visible from the outside what is happening inside the room - but only if you really stands near the glued window, the further one is away ( from about 1 meter) almost nothing can shine through to the outside.
Good, high-quality film, which is supplied with carpet cutter, fine lobules and large knife.
Absolute buy recommendation!
