The film could be applied easily using the supplied tools (microfibre cloth, adhesive fuzz, small plastic card). It has only a small bubble formed, which was but after a day and completely disappeared. The iPhone looks to the film also equal very different. With something like the more matte appearance and fingerprints are greatly reduced compared to the iPhone without foil. The reflections take off sharply. Even in strong sunlight, if you absolutely can not recognize without film, one has a good view here.
The only downside is, as already described by other buyers, the reduced sharpness of the display. You have to decide whether you can do without in favor of reducing reflection on the sharpness to give. In my case, the film is worth absolutely, because I just when cycling for Roadebike or when geocaching much outside use my Iphone and me because it matters more to recognize the display in any lighting conditions.
