These are a universal mount. IMHO this has the advantage that the Desire may remain in the protective cover - in a special holder, this is usually not possible. The holder can be mounted in two directions on the gooseneck. In one direction, the holding jaws sit slightly higher and then press on the lateral. Volume keys of Desire. I have therefore mounted him that the holding jaws sit down. There is no key hit and held the unit still good. The gooseneck sucks how otherwise expected from HR, bombproof. When driving the holder is placed in slight vibrations - if this bothers everybody has to decide for themselves.
