I was initially a bit confused by the rather low price; whether for his money and get a decent product. These concerns have not materialized to happiness. The quality of workmanship and the materials used is very good. Not even a slight plastic odor (or similar) I could perceive. Also the red "mumbi" logo on the back is firmly seated in the recess and does not project. The fit is very good, but encloses the iPhone is not 100% accurate. Since my Iphone (rear) is white, looks to the left or (!) The right side at the front now and then a very small white strip out because the shell is a little more relaxed than at the corners on the sides. But I still can not see any regularity in said optical interference, in other words I can "press" the shell and the small white stripes disappear for a day (maybe the shell must first adapt !?). However, the corners fit as I said to 100%, are stable and keep the envelope without wobbling on the Iphone, so the slight drawback with the white stripes barely noticeable. From the slip resistance of the material (especially on the back) I had erhoff me a little more. While it is a significant improvement to the enormously slippery plastic on the back of the iPhone, but still not "insurance" against the fact that the smartphone even slip out of your hands. Since I was allowed to experience from other cases seen better "slip properties". The shell is also not overly thick, so you can still enjoy the sleek design of the 5c. The recesses of the envelope for ports are sufficient and ensure all the normal functions, and also the buttons for sound or On / Off can be pressed without (significant) additional effort. All in all a solid product! Buy recommendation!
