The idea is good, the implementation is not. The glare protection consists of two parts. A frame is adhered to the display. The actual anti-glare snapped into the bonded frame. By slight lateral displacement is to ensure that the anti-glare firmly seated in the frame. This works but unfortunately very bad, me has fallen in the first 2 days of the antiglare several times, without that I would have touched him. Seeking me now something new. Fortunately, the bonded frame can again easily be removed from the display.
