Applying just the Sony Xperia Z2 mobile phone is relatively simple because the mobile phone is waterproof, you can hang up the sheet wet and then push out the water. To succeed in a blow and dust-free laying pretty easy.
The fit is good to very good, the back cover does not quite fit the camera but it is not wild.
With the front cover I am very satisfied, it fits perfectly and remains scratch free. However, you can see every fingerprint on the film, the description on Amazon promises that fewer fingerprints to be seen. I also sometimes have problems with the touch screen, it reacts partially easily delayed or has a life of its own. I suspect by anything on the slide, there is such a command.
From the Backing I am against not thrilled besides the somewhat poorer fit this is also very scratch-prone. After 2 weeks I have 5 deep scratches in it. Use the phone very careful and scratches can be created only when I push the envelope in the mobile phone without jeans pocket. This is probably related to the Härtgrad the film together and Numbi vertraibt only soft films. I probably need a hard film or the phone would just in a pocket, but then I did not need film.
There probably were increased complaints about the quality of the films, Numbi has sent to me without asking two sets of new films and then asked me again in my opinion. The staff were very friendly and nice and the service was top. Although the new backsheet also has scratch again. The staff then told me that there are different degrees of hardness and the Numbi only one Expel. As compensation, there was even the money back.
The assessment is mainly due to the scratch-prone back of which I am highly disappointed and quite strongly absorb the films fingerprints. The film was on a Galaxy S3 still really great on the Z2 restricted. But the service of Numbi is against class and that too without Amazon as an intermediary.
