The lower "holders" are merely a Einleghilfe / auxiliary support, even without (movable and degradable, also the head-mountable) holding the iPhone well.
The setting options ensure that it always sits perfectly.
Only the long "tower" of the suction cup can possibly interfere in many car. (1 star deduction)
Connections can easily be reached, and the loading and unloading of the iPhone works as it should. Quickly and safely.
The anti-slip mat is with me still in the room, as well as the hard adhesive ability for dashboard, so I could not test, I do not need.
Conclusion: Satisfactory holder, safe and stable, good connections ererichbar, sucker tower possibly somewhat bulky..
