For now the best

This is the best protection I could tested for Z3c. It is not perfect but I have not found better this time.
There must be a magnetic charger must be removed if the check each charge but for me that's what I wanted.
I cut separation between the power button and volume as embarrassing to the touch.
Its biggest flaw is that it is not suitable with use of a glass or plastic screen protector because too adjusted. When pressing on the power buttons and volume to this effect to take off the screen protector.
