This wasn't worth the money in my opinion. I'd rather get a two or three pack of something else (next time I will). The instructions tell you that any imperfections will work themselves out in a few days after you've installed it, but that is just not true. Mine has what looks like (but doesn't feel like) little bumps all over it, left behind from the squeegee that came with it. Also, despite being EXTREMELY careful, there is lint trapped under it. I see no way this thing will last "the life of my device" so I saved the packaging and receipt so I can return it when it fails (it has a lifetime guarantee). It does seem a bit tougher than normal screen protectors, but the material has a lined quality to it (like corduroy) and I think it affects the clarity of the screen, especially of white backgrounds.
