Assembly:
I have attached the film immediately after removing the protective film factory. Also has the same work the first time. Especially helpful I found it that has fallen directly on the screen when attaching sunlight, then fine particles be detected and cleared.
Function:
Fingerprints significantly reduced (compared to the demonstration with no film in the business)
Reflections significantly lower than without film
Indicator is still clearly visible, even in fine detail
Very robust against physical influences
