Have the films now for about 1.5 years on it (the first held about 10 (?) Months) and am really happy. At first I thought the slight flicker would bother me, but it is not really like that. Is halt ne matte film, so you can see it too, but it can be seen in direct sunlight evenly also something;) Stable it really is and when to install it according to the instructions, also form (almost) no bubbles.
I would definitely buy it again, but I'll try next nevertheless again the clear = D and eventually falls yes certainly "the stone" apart ...
