Meanwhile I own 2 of these great cases. I can just say that the shell is perfect. She sits well and the iPhone is no longer misses out of my hand, so I can save myself the glass damage, which I had with my last Iphone otherwise. Edel I also think that the "color" sound alternates depending on the light. The buttons are easy to operate and the mobile "contributes" hardly ;-). The material feels pleasantly soft. The investment has really paid off. I am more than satisfied. 6 stars !!
