By the way I needed two attempts with the film, because at the screen size, the film was twice unfortunately put a little bit wrong at the beginning, which is no longer correct. Because it helps only to venture a new attempt (with the result that more and more dust accumulates).
2. The film
So the anti-mirror effect well as on a matte notebook display. The brightness of the display is hardly affected by the film. However, a change in color I can confirm - Blue is a purple.
Unfortunately, the film is also sensitive, that is, by attaching the foil (above and following the instructions described) is easily "scratched" - even though I had wrapped on the map The included duster. These strips are hardly seen in Betreib - when the screen is off, however, this does not look nice.

For the anti-Spiegelefekt I give 5 stars for the sensitivity of the film ("scratched" with stripes), the color change from blue to purple and the attachment that is not possible, unfortunately, without dust, I pull back from 2 star. Stay: 3 stars.
For the price and the value probably akzepabel, but I would not do this procedure of applying again.
