The phone we are laterally fixed by the "talons". The claws snap into small intervals and keep up with the rubber pads the mobile phone firmly in place. This works surprisingly well and the cell phone is held up well even on bumpy roads.
The support we fixed with the usual Sauggummi on the disc. The rubber sucks thanks vacuum tightly to the wheel and holds bombproof (In the beginning, my mount but after one day dropped now holds already for two months). With the built-in ball joint can rotate the mobile edition free and then tighten it to the wheel.
Three small Verbesserungsverschläge I certainly have:
1. The lateral claws are not centered, especially in large or long mobiles the phone in landscape mode is then held only on one side. Because you could have built the two fixed support feet as withdrawable "claws".
2. I have my phone in landscape orientation in the holder. The button for unlocking is then either the bottom right to the holder or when I turn in the top left. Both are not so easy to reach for me. Here you would be able to realize the release of two opposite buttons.
3. The arm is permanently mounted on Sauggummi and not adjustable. A ball joint at this point would bring even more flexibility in mounting.
In sum, the criticisms are not sufficient for a point deduction.
