Apparently this is the original carrier. Good resistance on the air vents (Toyota Yaris) and Renault Grand Scenic (although they are a little behind the holder locks properly position). Good performance of Lumia 930 smartphone (maximum possible size for this support). The weight of the phone does not affect stability. All of support or fixing surfaces are sufficiently flexible material to avoid marking the telephone or the clamps aération.Les grids pass right between the on / off button and the picture button. With a few days of practice you can insert and remove the phone easily by building on the clamps without the support does shoeless grids.
