As extensively described, it is hardly possible to place the film precisely. She quickly gets to far to the edge, where it is pushed and lifted by a silicone sleeve. A frame-filling measure the placement would have considerably facilitated. Thus, I place the trimmed liner requirement in question.
Furthermore, it is hardly possible to apply the foil without bubbles. Experienced professionals, this may be possible. Me this was not possible as an average talented amateur. Even the edges of the film have kept bad, what the effect of the silicone sleeve again reinforced.
By practicing the application of the film, the first copy is then at once worn. In the second and thus last film I was much more tolerant with regard to their optical effect or the mobile phone. I've kept simple, as it has pasted the first time. But something else is nice ...
After four weeks, then the film was also attacked striking or picked up and covered with scratches. I definitely am not a power user, this life is out of the question; the cost in the long run not to mention. Only that the film does not limit the function of the screen or the pen and actually prevents scratches from the display, justifying three star. The handling and the optical effects are very modest.
