Screen protection with great feel, but not scratch resistant

I have this screen protector for my Ipad Air ordered because I have done with this type of screen protector on my Iphone very good experience.
Basically, the cutting of the film well so far, but the edges are not as nice as the smoothed competitors product. Even the contents of the package is the further behind, here is only the screen protection included without any additional aids.

Now, after three days in the use I have to realize that even have crept first fine scratches, although I additionally use a shell with lid.
For a scratch resistant screen protector that is advertised unfortunately insufficient.

Overall, the feel very nice and the screen protector visually nice, but because of the not so nice rounded edges and the first scratch, there are two star deduction.
