"Originally designed for the military to protect helicopter blades from sand and dirt", the text promises sensational package. When unpacking the film is clear - who take very seriously. The films are individually welded, it is a 30-year warranty card that also serves as Aufbringhilfe and in my eyes the hammer - "Shield Spray". A small bottle of spray, what to spray on his fingers before application to prevent fingerprints. As you know in any case where the 20 are back.
The film comes in several parts: We have a front and two single small narrow strips for the upper and lower chrome frame (can not overlap so, because of the edge), and a back with streamers on all edges. The latter has enormous in itself, but more on that later.
To apply one has to be said, without time and skill as it gets! Those who do not exercise in patience, will mess up his film irretrievably. Clear it can again be removed and reapplied, but not indefinitely. The device must of course be perfectly clean, as well as the hands and the environment in which the film is applied. After lightly sprayed with spray the parts, you can fix it and apply slowly and correct if necessary even a few more times. One should "to exercise" with the front start, because this is quite fast and easily applied bubble-free. For the back however it takes almost a PhD - it covers the back and the side edges of the device from one piece, which makes it very difficult to apply them easily. First, the part has to sit on the back itself neatly and then the edges must be folded. I had just then spray and tighten various problems with the adhesion of the small edge portions, but also helps here.
After that you should let the machine according to instructions as possible one day lie unused, from personal experience I can say one night well enough. Smaller bubbles disappear after two to three days, more can still try out push or alternatively puncture minimal.
If you do everything right, you will acquire here a doubtless high quality film which is hardly noticeable and affects the operation in any way. The touch screen does not feel to some extent different.
Of course, the screen of the iPhone is also relatively scratch resistant unprotected. Whether and how to want to protect your device, then must ultimately decide every self.
