The protectors are absolutely well. An exact (illustrated) Description for installation is included. I think that however much easier is: Cleaning the display is logically necessary, an appropriate cleaning cloth is included. To get the latest dust particles from the screen, I'll take a piece of plastic wrap, which is present in every kitchen, and put it on the display. The actual film is provided on both sides with a protective film. The back protector I remove not completely, but Be moved from the upper longitudinal side slightly by 2 cm downwards. This ensures that I do not have long fingers on the underside. The cling film I remove at the last moment. Now I can create the film on the upper longitudinal side exactly. I was not the same happy and have repeated 2 times what is possible. The protective film on the back then I pull away completely and the front I remove at the end as well: perfect! Absolute recommendation!
