Problems at the corners

In my opinion, a micron is too large, the film. The film is easily and without bubbling to "mount".
However, in the corners, it is not possible, this film purely zubekommen, somewhere you are at the corners always a hint about it.

Addendum;

An employee of HandyNow has again set a send films to me probably because of my review.
I got the hint that there was a technical uncertainty, through quality control.

These films sitzten now all around better.

Respect for the very good customer service. Thank you to this point.
