Not the first time I use Expert Shield and am thrilled. I always use the "anti-glare" So the "glare-free" or in good German: matt version that, so I find a lot better still apply, in contrast to normal and not just protects the screen but also in the sunshine makes the handling more , very important. With the accompanying microfiber cloth the display really has to be spotless and not remain a speck of dust in micro size on the display as described in "clean room conditions in a chip factory". The manufacturers recommend the bathroom because no dust is here by the humidity in the air. But it is also like that. Good clean, the desk lamp embarrassing examined closely and then hang up the film. Toll!
