The Smaak magnetic air vent mount clips onto a car's air vent louvre and holds your phone with a magnet, so you can put the phone on and take it off with one hand. A thin metal plate goes on the back of the phone or inside its cover, and the magnetic head grips it while you drive. It keeps navigation at eye level without blocking the windscreen and leaves the dashboard free of adhesive. Smaak's related Flex magnet mount uses rare-earth magnets and is rated for devices up to 250 g; the exact rating and plates supplied with this vent version could not be confirmed, so please check the packaging.
