The application was - unlike films - very easy to handle. In normal light, the visibility is good, the picture is very clear. In very bright light but the screen protector reflects more light than it did the display without protection. In a very bright environment you should increase the screen brightness set to maximum in order to improve readability. The reflections are a bit disturbing, but also turn not extreme.
Since I'm always on the display when you look through the viewfinder with your nose, I create by a slight fat contract to the screen protector. Unfortunately, it is so that these fatty order can be seen better on the Delamax screen protectors and leads to stronger reflections, as it was the case with the actual surface of the display. In addition, the oily film from the glass can be removed more difficult than is the case the original display.
Because of the pronounced reflections and the more dirt adhering I forgive only 4 out of 5 points. For the life of the display protection of course I can not say anything because I did it only for 7 days in use.
