Very appropriate size, easy installation, relatively fragile

No difficulty encountered during installation.
The film is very thin, measuring the same size as the millimeter to two tenths of a screen near and does not reduce screen brightness.
Back after 6 months: The film is horny relatively quickly from the moment I regularly brought the camera to the shoulder hike.
I rotated the filter for the horny edge top of the unit, thinking of a bad arrangement, but a second corner quickly horny too, the film eventually come off completely.
I think taking a rigid film to replace him.
