An important criterion is the handling during application, the film is verhälnismässig rigid (fixed), but the application was therefore very easy and bubble-free and possible at the first attempt. If you proceed according to the enclosed instructions, no problem, I even had not even cross out any bubbles, which in turn I clearly attribute to the rigid foil ...
The protector itself is dull by their Antirefelex properties, but this in no way interferes and leads to the above-described advantageous properties. It is so hard that even permanent use do not mind you keeping us always more than 1 year with regular use.
I am completely satisfied, so there is full 5 stars!
