Applying the foil is no problem for the experienced Folienaufbringer. The film can be as easy / difficult to raise as any other "brand film".
The quality of the display with slide is also anti-glare typically perfectly fine and is easy to read especially in direct sunlight and reflections in the background.
Unfortunately, the film is absolutely not as scratch resistant as comparable films of other manufacturers. I have already after about 2 weeks of normal use some deep scratches behind some slight scratches front.
I'll keep this foil until further notice it and can it for the transition to other manufacturers better deliverable films have recommended. But I'll definitely buy a new slide.
