The Bumper sits beautifully at attention on the device and makes a high quality impression. It protects against slipping on smooth surfaces, but is not as dull as softer Gummibumper so that the phone is still good to get in z. B. pockets. All controls let good and easy to operate, and the on / off switch on top of the phone can be operated well. Difficulties I can not find. Conclusion: usability, appearance and fit are good. Therefore, a clear recommendation.
