I do not understand the problem.

I have, in spite of rather subdued reviews, mainly purchased on the mounting the film.
The film came in a pack in a plastic bag and Papkarton was truly quite "loaded".
I then dusted with the existing microfiber cloth first.
Other preparations were the display with microfibre cloth to clean this all the windows, wearing rubber gloves so that there is no finger slippers, face / mouth / respirator so I do not pruste sheer breath hitch and sudden ejection of the dust back to's display. Ultimately helped me even a scary Druckluftdose, with one especially the corners got good clean.
The assembly can be quite well alone hinbekommen. I also had no help.
The first attempt was virtually perfect dust-free, unfortunately sat de Folie not quite straight. So again and another attempt, this time straight but unfortunately a few small bubbles and two minimum stamens. The bubbles could be absolutely easy and residue-free push outwards. The two threads and therefore continuous air could push away like a pimple, thus the air, the yarn was gone indeed included but basically invisible, as the entire air was gone and the film sat directly on the display. Really, am otherwise very picky with me and the material). You can also press the remaining relatively fixed on the screen to just push away the bubbles, which do not mind and apparently the film is also a little permeable to air.
From the effect of Antispiegelns I'm thrilled. Finally sitting by the window to look without changing the position where one throws himself on his own shadow's notebook.
The scratch resistance is great. You can tidy it rumwischen without there scratches.
I highly recommend this film!
