is what I was looking for 1

The goal was to have a bumper + back protection. The concept of this hull is perfect, and seemed more qualitative than competing models.
The fit is very good, and plastics are of good quality, particularly the textured back that improves grip.
My fear concerned the clutter: I had the same shell on a HTC Wildfire S, I was satisfied but clutter was very important. So I was pleasantly surprised with that of Z1C, since it remains relatively quiet. That said, it's still a rather imposing hull, do not expect something very end (there are other models for that).

The main problem risen by some concern the lack of openness to the magnetic socket; I think the problem is more at Sony, which has a good idea (the magnetic port) but offers only ridiculously expensive dock, and incompatible with the majority of cases. And magnetic cables that can be found are not official. This absence is not surprising, and seems justified (it is clear that even with an opening, the shell is too thick to fit in the dock); I chose knowingly anyway.

Is the price: more than 25 euros for two pieces of rubber, even well-designed, it is expensive! Hence the star less ...
