After not quite 3 months me now is the lower clip from Kunststofframen which holds the mobile phone, also canceled. Thus, the shell was useless. After such a short time that's too bad even for the price.
After a brief but friendly contact the dealer but I got immediately a free replacement. For the great service so gibs an extra star.

==================
I wonder for a long time that the whole localization with my phone is so bad. Especially the compass shows anywhere, just not to the north. Now why I even had my cell phone in the repair. After much wrangling, I note that the shell (presumably the magnetic closure) interferes with the sensors of the phone. Since I am dependent on the geocaching accurate location and direction determination of the phones that shell is useless for me! That's reason enough to cut down on a star for me. Especially during geocaching a shell is more than important.
Conclusion:
+ Looks elegant
+ Protects the phone enough
+ Fast shipping and good service
- Does the location services, particularly the compass
- Magnet flap very stiff
- Plastic too hard and thus fracture risk
No buy recommendation from me! Who buys cheap, buys twice.
