It protects well as it should back and all edges of Sony Z3 comapct BUT, when all outlets are available, one for the magnetic charger is covered in half by the plastic. For the price I did not want to take my head to send etc ... So I cut with a cutter to widen the hole without weakening too much overall. So 3 stars only because this hull has qualities but for this copy in any case, they should have tested for Z3 compact from Sony. (If he was not jsais how they were able to miss that)
