For me, the thing

The quality convinced the color is actually quite nice, although I wanted to have black before - the hard shell on the back is almost bronze - looks elegant. The cover on the battery makes the phone a track wider than the original cover, this is due to the increase in the camera better protected. The current price is more than ok.
For me it's the right product, especially because you can make calls with a united front - which protects the screen from the skin film, which otherwise is transferred to the front. The leather cover can be folded down completely. So you can also wear the device well with one hand and secure it were by holding the leather cover with two fingers on the back of the phone while you type with your thumb. The still relatively large device is thus stable in the hand and one is hard pressed down.

One star deduction there for protection. The screen is protected against scratches, but I did not feel that it is much better protected (mainly from the rear) when dropped or before other impacts or shocks when compared to the original state. But since I have an appropriate handling of my device and it is not very much (eg professional) claiming, for me personally the protection is enough.
