Attachment completely simple and bubble-free - long-term test is still pending

First, I was surprised about the large envelope, in which the film was packed. When unpacking the entire contents has revealed:
3x protective film, 1x Microfiber cloth (!), 1x knife, 1x assembly instructions

Wow, this is really extensive, top for "I sometimes just buying a screen protector".

The application of these films has been so cost me in my life some nerves. Either stick these things do not or immediately so well that a correction is no longer possible. In addition you can in most films doctoring as much as you wil that bubbles just do not disappear towards the edge, but share more than doubled and the problem.

This product is completely different (thankfully)!

First sitting of screen protection at a reasonable support of stable film. On the top of the screen protector is protected by a further thin film with square grid pattern.

First you clean the screen with the supplied cloth. Then pull off the thick carrier film and is the protective film on the display. Alignment is completely easy thanks to the square grid on the upper protective film.
Now you pull from the upper patterned foil.
I had only a small bubble right in the middle. But which could be wonderful doctoring the brim.

The screen protector makes a tidy stable impression and is provided with a matte finish so that reduce reflections.

Whether and how long does the film remains to be seen.

So far, I'm thrilled. Quality top, top mounting, top price, ergo => Review top. 5 star and Recommendation (conditionally on the long-term test, I will write in updates here)
