OK I keep because I was with sows off returning and I have torn the package.
When trying out I noticed that my original Smart Cover is apparently destroyed in the process, because the real grip clip extremely strong.
That what most bothers me though is always covering a button or the charging port with the holding arms. Laden with a magnetic connection is not possible. So begins the next fumble into the USB port.
If you then try to use it the other way around then you have the A covered off button. No matter how you try, either is pressed the camera button, volume keys or the A button.
Pity and a big minus on the SONY who do not get to the series for your Z series offer a bracket.
So summary:
1.Entweder a switch is held by one of the arms.
2. the Off button is held.
3. With magnetic loader impossible.
4. Make sure that no original Soft Cover (SmartCover) can be used which is then torn quickly. With me after the 3rd attempt :(
So the less handle on the side are the better the use to.
