I had only my doubts. In the protector for my 3DS, I had some problems with air bubbles and fluff (although 3DS also only freshly unpacked), but here everything went by itself and not a single bubble in it. Either Mumbi has bolted to the film, or I have now simply more of practice. As mentioned in other reviews and the film products is a bit smaller than the display, so that it fits well and does not inadvertently apply pressure (which would be seen as a touch input). The difference is - centrally applied - but really minimal and hardly noticeable. As also set it to excessive amount of dust or dirt. Otherwise, the film is so far great and are nothing to complain about.
