Adaptation of Z3 not well solved.

In the advertisement, the adaptation of a Sony Z1 - Z3 so simple.
Fiddly it actually is. You have to look carefully already, so the smartphone is properly seated on the contacts.
The contact strip is designed to be movable and not stay in the position after removal of the smartphone.
This is a necessary in every placement procedure, to find the right setting position again.
In addition, I have found in this case, an already opened protective pouch in which the docking station is wrapped up.
Both are my reasons for returning.
