As against the "cover" does not close properly.
It opens itself because the measures seem ill calculated for the Sony Xperia Z1.
Not possible to recharge with the case. It must be removed to gain access to the terminal and its valve open.
It is not possible to take his mobile with one hand.
We must fully open the lid until the cast completely in the back. And to do that you have to use both hands.
It lacks a busy loop with clips or Velcro to pass a belt and have a sleeve to size.
