The mount itself looks quite robust and high quality of (have for the warnings against counterfeiting consciously directly from Amazon and not ordered for market place traders). However, the holder is in conjunction with an unsuitable iPhone 5s for the Opel Adam. At the slightest vibration, the grippers slipping out of the vent. Because the bead on the dashboard above the round fan, the grippers of AirFrame can not engage properly (they grab only the movable blades and not extend to web) and not hold. The blades fold down and the iPhone slips down. So I'm sorry, I have to return the holder.
