Excellent support that fits perfectly my iPhone 4S. It does not move at all. And it fits perfectly on the vents of my scenic 2. Very easy to put on and remove the support. Two hands still necessary. This really take five seconds max. The support is also easy to remove, 3 seconds max. And as for the back. Once in place, it really is more moving. Think about the push from time to time because by dint of place and remove it as it happens that the media moves a little. Great buy, low prices, very small, the ideal medium. I have since 4 months. To see in time.
