I will start with the fit.
The recesses for the "Home" button, the light sensor, the speaker and the urge camera are absolutely perfect fit. One can, for example. The cutout for the speaker used for aligning the protective film.
Which brings me to attach the protective film.
Since the film accurately fit on the display, is the install without any problems possible .... at least in theory ...
but then when it gets a speck of dust when sticking hiss display and membrane they must back down, or at least a part of it and it starts a renewed tried.
This happened to me often and I have to say, no problems, it was possible to withdraw the film again and again and to bring again on the display. This demonstrates real good quality because I had very different films that had a crack after the second attempt.
Possibly resulting bubbles can be easily pushed with a credit card, which is wrapped in a micro-fiber cloth to the outside. (If there is no speck of dust or booze is in the bubble)
Finally, the scratch resistance and the fingerprint sensitivity.
As mentioned I have the film for over a month on the phone and I have as yet not a single scratch on the film. The display is not kept during the transport in a mobile phone case or the like, I have to the housing only a Silicon Case for protection.
As with any touch screen cell phone fingerprints are left on the display, which can not prevent the film, however briefly cleaned with a microfiber cloth or the display and already there is again a clear view of the screen.
Furthermore, I must say, that stands out as good as the screen protector on the display and distorts the colors or brightness of the display in any way.
All in all I have to say a great protection at an affordable price for the display since the offer includes two screen protectors.
