I ordered these films some time ago. I was clear from the beginning, that is closely connected with a loss of quality of displays, because let's be honest how else the Anitreflex effect should be able to function. The quality is still very very good. You hardly notice a difference at medium and highest brightness setting! -> My personal opinion to those who criticize this: It is and remains a film which is located on the display and it is quite clear that the film can not be fully realized or there would be no anti-reflection! This then is a minimum loss of quality, but who does not stick to the eye directly on the display should have no problems.
I had a few problems with attaching the protector which is probably due to my own stupidity or precision. This had 2 of the 3 films no longer usable. I then contacted the customer service. There I was immediately helped me and replaces unusable films. In the new film there was then a grid to facilitate the placement. And I also tips were added to mounting.
