The film is slightly smaller than the display, which is why they could be applied very well without bubbles. When, if not a protector would be applied to the display sheet. This is dissolved only after the screen film was brought to the screen. Unfortunately, you pull this back again from the display, then has dust and bubbles under the screen overlay. This can indeed resolve quite well with the included auxiliary tools, but unfortunately shifts the peeling of the protective film, the screen overlay on the display, so that it no longer fits. Therefore only 3 stars.
