After a short use dull spots!

The attaching the protector was indeed really easy and also the delivery is exemplary for the price. But unfortunately, the film (after less than two weeks of use) already become dull to often wear points ("back button" right "scroll area", "dock bar" keyboard area).
Ok, we just winter and my fingers are by now certainly not "silky smooth", but that should be a protective film with:

"... Very robust, durable and developed for continuous use! ..."

advertised surely endure easily! I had previously been (partly significantly cheaper) films on my smartphone and this phenomenon I had never! Due to the many good reviews here, I suppose it was a production error. I'm going to tentatively raise times and see if this is also as quickly dull the second film ...
