For a black compact z3. The smoke transparent shell is correct. The covers are accessible. However, disappointed by the accessibility to the magnetic connector. With the magneto I bought the hull is too thick and the connector plate is not great, but still charging. So disconnects more easily. So I had to use the dremel to refine the lower side of the plastic window. But also the upper plastic bridge. Choose a short magnétor that is on the end connectors and moves away. Otherwise, the advantage is that it smoked does not darken with time!
