Since the film is relatively thick and hard, I think that it protects well, but I made in practice have no experience with scratches. The film was bought preventively from me, even if the Kindle is transported as possible protected. Due to the price advantage, I ordered the double, although I do not think that I will soon need the second film.
Overall, my film was released as a protective sense (even if you probably do not need when you're transporting the Kindle in a shell) and in my opinion it will also fulfill its purpose. Since they do not also changed the look, I forgive 5 stars and would recommend this protectors.
