This support is absolutely genial. It is only laid on the dashboard and does not slip. No need of a suction cup on the windshield that dirties it and indicate to thieves that you have a GPS in the vehicle. In addition, the GPS is much closer to the driver. This is very convenient (although in principle we should not use it while driving) especially on a vehicle with an array of very wide brim, a camper or a van, for example. Very easy to store. Very good investment
