Mounting difficult poor durability

First me, the film was misbehaving even during installation. Because so hard you tried, but I did not manage to mount the film without blistering.
If you have to first get used to the bubbles, the operation works quite well. I have found no restrictions on the sensitivity of the touch screen.
But after a few weeks you can tell already that the film on the front begins to dissolve. Is a first corner loose, it then proceeds rapidly, as more and more dust and dirt accumulates between the film and the screen.
Meanwhile, it is useless and I have a new, but others order.

Conclusion: I would not buy again!
