Already, the packaging is really neat, it's just like a detail but pulled out for that, hats off to them!
In terms of support, it adapts perfectly to a grid of ventilation of a 206, and my iPhone 4. Once the phone in place, the gripper holds great without the wreck through the gum covering the support. Another good point: my windshield is not cluttered with a suction cup ...
One area of improvement could be to facilitate the opening of the pliers to remove the phone. Currently, it is not very ergonomic, even if it is done very well.
