I was the first time the product Ã'berhaupt not satisfied, because for me bubbles (no dust particles) on the protective film were (which is not even attached). After that I was a very nice woman named Susanne written by Customer Service and offered me to send a new set as anchor puts a very high value on customer satisfaction. Today the new set arrived, and lo and behold, before and after applying the protector were no bubbles present.
I think that can happen before, and thanks to the nice customer service, the problem is fixed.
I am now very happy with the film and again many thanks to the wife Susanne.
