Suction cup phone holder
A suction cup phone holder sticks to the windscreen or a smooth dashboard surface with a suction cup, often on an adjustable arm. It fits most cars, but on the windscreen it needs placing with care so it does not block the view of the road.
Suction mounts are popular because they fit nearly any car. Heat and cold can loosen the cup over time, and on the windscreen the phone must sit where it does not block your view of the road and traffic ahead.
SSUCTION does not make suction mounts, despite the name: our mounts fix to the air vents. See the windscreen phone holder entry for the placement rules.
