The attachment is not so easy. It comes with a detailed manual, unfortunately, is the German translation unhelpful. Here, the manufacturer would have times someone should ask who speaks the language, very embarrassing. With the English version of the guide, I ended up being able to install the foil. The difficulty is partly because they align properly and in preventing bubbles under the film. I got the film very well positioned, but unfortunately a few tiny air bubbles remain at the top. In summary: It's got to have a little skill to bring this film properly.
One point deduction, there is a small sticker on the front of the film, the only one informed about that this page is the "front". This sticker can be difficult to remove, leaving adhesive on the film, which must be rubbed after attaching the film first.
Once installed makes the film but then a very good impression. Yes, of course you see fingerprints on it - when the smartphone is turned off. So, as in the normal display halt also. But as soon as the display is on, these fingerprints no longer fall on. This gives a very clear picture, the touch features are very good, the film falls not continue in operation.
Summary:
+ Good protection
+ Is not noticeable in operation
+ Good picture
+ Touch functions work fine
- Attaching something Frickelarbeit, as with any film of this type
Buy recommendation: Yes!
