Not quite convinced

I bought the protective film because I wanted to avoid scratching the glass in the first place on my new smartphone.
The film does, of course, what they want, they protect. Nevertheless, the negative aspects are more serious to me than the positives, so I will probably not use the slide continued.

Positives: excellent protection, very good fit

Negatives: touchscreen responds very poorly against the description, fingerprints are more seen as directly on the touch screen and are also more difficult to remove. Moreover, I have to install it free of bubbles despite several attempts and exact observance of these instructions, the film failed at the edges.
(Perhaps it is well to me).

I would buy my product but certainly not again.
