I bought the display along with the anti-reflection film of the same manufacturer. The film keeps what it promises: No quality loss compared with display without membrane. But if you have previously a reflective display, it remains that way. If you do not want, should resort to the antireflective, but this slight quality losses has respect. Sharpness. There are at the antireflection no problems with fingerprints and the slight graininess of the display you get used to. Who reads a lot, for this could be a little tiring in the long run, especially in small print. Otherwise, it does not fall on. I can fully recommend both films. You have to decide whether you want to put in its everyday use rather focus on a razor sharp image or a few to no disturbing reflections (eg travel a lot with diffuse light) itself. For the price I can but only advise to try both. Right now I have again the Crystal Clear it because I read a lot. But I think I'll go back in the summer. Incidentally, this is the good thing about the films: They can be as often decrease again. In "Dust attack" simply rinse under the tap, the water gently shake slightly and back on the phone bring - the film does not even have to be completely dry. Water inclusions can be pushed without residue to the edges and suck with a cloth.
Another tip for attachment: In the meantime, I need not even have a credit card to be mounted. More important than the uniform press is 1. the absolute absence of dust (even the smallest particles ensure unsightly inclusions) and 2. the exact placement at the beginning. My tip is that you do not first attaches the top of the phone. Since the film is extremly fit (a deviation of 1/10 mm or even less - at an angle or too far away from the edge already leads to problems), I use the continuous (ohen cutouts) bottom side of the film in 45 ° angle so the mobile phone, that the edge of the film closes exactly with the slightly protruding edge of the phone (the longer sides, I think this between your thumb and forefinger). Then you can gradually reduce the angle and with the other hand press down slightly / help out.
If it is not the first time succeed (dust inclusions, an angle, fingerprints on back - do not panic slimming (with the fingernail of a corner her constant exert pressure towards mobile center until the film releases), rinse and try again underwater. My film sits knotless and I need a change now for detach and attach
