The kit has several pellets to stick, degreasing wipes.
The double-sided tape on the back of the pellets is very effective.
The X-shaped bracket clings to the gates (power) of the vehicle's ventilation. Then just turn the magnet to a certain block.
Once in place the support shows no play.
The phone sits simply on the support.
If there is no element s of the car coming hinder the rotation of the phone, it can be positioned in the desired direction (depending on the location of the USB connector).
Turns, speed bumps or hens nest do not disrupt the stability of the phone.
Last on the magnet, it does not disturb the GPS reception quality (waze or google navigation) my phone.
However, I have a shell on which the wafer is bonded.
There is a "technique" to unhook it. Otherwise the support comes with the phone when removing it.
It takes (for me) to slide the phone to one side and not get shot. Thus the support remains hanging to the fins of aeration and phone comes quickly.
The price is quite fair compared to automobile physical stores.
My only "pain" comes from the color of the two larger pellets that are gray metalized while the smallest are black and more discreet.
