Adequate at best 4

Difficult to compare with another product of the same kind, it is the first that I use. No more difficult than to stick her, but full of tiny bubbles. And yet I really paid attention. Finally, a protective film that protects scratches but anyway a little too easily in my opinion. In any case more than the original protective film. Its worth the money, but no more. For sending and packaging, nothings wrong, fine. So a cheap solution, but not necessarily top-level quality.
