- It does not protect the sides, your Z3 tomb, pray for it is nothing;)
- This is a protection that is adhesive, ie that sticks to your back or almost Z3, it quickly takes off, enough that you are lying, the phone above you when you visit ... and BIM the phone takes off and goes right into the head (I am a witness). And sometimes it even enough that your phone is slightly tilted so that it takes off.
So for that price, I advise you to look elsewhere ...
