Used first display film ever ... and equal to all 3

I was a bit skeptical, especially after I read the 2 but very different reviews. This is the first time that I have a protective film installed on my smartphone. Since I have also used the same all 3 films of this pack. The first 2 I had to settle again, because lint and bubbles under the film were and did not work now. At the 3rd time I had the hang more or less out (a klizekleines bubbles is unfortunately still came to the side and does not go away). But I had no problems with adhesive residues, either on the screen or on the film. For the price it is perfectly okay. Remains to be seen how it is reflected in the long term (the film did not have any time on it).
The film is from the feeling rougher than the mere display and you hear the finger when it sweeps over it - no idea if this is normal.
