The shell surrounds the iPhone perfectly and sets in the right places on additional air cushion and thickened in order to protect the device at all times from scratches or even damage from falls.
The air chambers are intended to support the buffer function and thus absorbing the fall, which of course I can not prove 100%, but with the recent falls the envelope I was reliably protected against a certain damage. Doing so also it feels a lot better than a lot of cases, which waive such a technique!
Of course was also designed in the right places at the cut-outs for camera and connections.
For me, the design despite the high level of protection is well done, as you can see the chic IPhone well through the shell. For my taste, something is much nicer than kitschy cases with designs that obscure the precious metal of the iPhone!
The price / performance ratio, I find appropriate for this good protection!
