To form:
The protective film does not fit in terms of size with millimeter precision, but it covers (up to 1-2 millimeters on said edge) the display. Another positive: The locations for front camera, speaker, etc. have to precisely matching point recesses; Thus, the film has no effect on microphone, speakers, etc. (thumbs up!)
For adhesion strength:
How strong the film "sticks" can be derived from previous reviews. Cause all again on this film sticks (small particles, hair, etc. no longer gets from you. This is what I found out when I tried to install and equally all the dust was in the vicinity, or on the display the first slide on the film jumped.
This could have been avoided if I had read the operating instructions (Yes, there is a manual !!!).
On the second attempt with a new film, it has then worked great (the screen was so clean now ;-) and is there now for over 3 months without showing signs of weakness at a single location. (One must add that I like to begin on something to play around, but this film you do not get so easily from where it rests for now.)
For quality:
The foil on the display can be easily cleaned, wipe with a damp cloth if need be. Even from scratch, it has preserved my screen so far, but I count that is not necessarily the key ring or the like is in the vicinity of the display.
Conclusion:
I regret to have some wasted the first film so, but I doubt I'll get the package blank before the phone gives up the ghost. I am absolutely satisfied and would recommend this product only.
A little tip from the manual: the application of the film or the like a debit card is best use to avoid Luftblässchen. So it worked great for me.
