However, 100 percent free of bubbles I can not confirm. Despite video it's just tricky to apply as a grope film accurately and without bubbles. A micro-millimeter deviation and you're hanging on the other side on the frame. Any attempt of repositioning then carries the risk that set of small particles on the screen or the film and you've got bubbles.
Basically, I am happy, even if I consider the generous promises exaggerated.
