Positives: Shell Size perfectly suited to Z3c. She appears to have the potential to adequately protect especially the corners (parts of the thickest shell) and also to protect the back of the phone from scratches. Negative points: Oops cutting / finishing on the right side and bottom. Do not adapts to the dock DK48 .. Even expanding the adapter, the shell is too thick at the magnetic plug on the side, which prevents the dock make contact. If I find a solution for you I would know.
