Does not keep all my expectations stand

positive (which speaks for the film):
- Accurate (not exactly, but so accurate that an assembly is no problem
- Bubble-free mounting on the first try (had already tried another ultra-clear film that was not Bubble free installation)
- Usability of the touchscreen was unrestricted
- Film was invisible; the color reproduction of the display without restriction

negative (which argues against the film):
- You can see every fingerprint or finger movement
- I was therefore constantly wipe on (either with a microfiber lens cloth or, if that no longer went with a damp lens cloth), after a short time the first scratches not the promised product properties were on the slide visible (ie extremely scratch-resistant (hardened surface ), Dirt resistant to fingerprints).

So I attached a matt, anti-reflective film today.
Advantage: No more fingerprints, disadvantage: The video playback is much worse (grainy).

Well, there has to weigh, what is a important. Most people think this is a film anyway unnecessary due to the scratch-resistant displays of home.
