Maybe you bought your cellphone mount in a gas station for $7. You needed it for a road trip, you mounted on the air conditioning vent on your dashboard and you’ve had it for years. But is it any good?

Vent mounts: They wedge between air conditioning slats.
Dash or window mounts: These use suction or adhesive to mount to your windshield or dash. Be aware that in 27 states it is illegal to mount a cellphone to the glass but you may be able to mount to the dash in other states.
CD slot mounts: These slide into a CD slot and latch on with a triggered hook. Many cars now don’t have CD players so these may or may not be an option.
Gooseneck holders: These plug into cigarette lighters
