After I bought the z1compact me and had the first scratch at the back was clear, a shell must be found. I did not deliberately cover to close. Since I do not have the dock were the negative reviews in this regard for me not decisive. So I ordered this envelope. What bothered me start immediately was that the shell is slippery. So there is not that a good grip as with rubber. Is made of hard plastic, I think. But what is a qualitative NoGo for me, is that the coating detaches from the plastic after about 1month. Now hang on little pieces of shell around. Accordingly, only 1 star, for the perfect fit. No buy recommendation.
