The Final Protection Protector for iPhone 6 (back) is really great. They fit exactly and can be attached very well. It does not cover the four corners of the I-Phone. The installation video is well explained. I needed for mounting about 1 hour. The first steps are done in about 15 minutes, then you have to wait until the edges stick to the curves. I waited about a 3/4 hour and then the edges have also stuck perfectly. With the film, the I-Phone can handle very well and you need no longer afraid of scratches on the back have. ;-)
