Cell phone holder for car. This universal smartphone stand is made of plastic that imitates leather. This helps it blend in well with the interior of your car. On the back there is a spring-loaded clamp, thanks to which the phone mount attaches to the air vent system of your car’s dashboard. Thanks to the gravity, the weight of your cell phone or GPS device pushes down the bottom part. This pulls in the side clamps, which are connected with springs. This simple but effective system holds the cell phone firmly and securely. The cell phone holder fits perfectly on the dashboard, without sticking out too much.
