360-DEGREE ROTATION: The 7Tech Car Phone Holder Magnet is the best in the market. The adjustable setting allows you to fit the mount on both thin and thick air vents. Simply rotate the PVC vent mount to get the fit you want. The anti-slip material means your magnetic phone holder won't lose grip on the vent or your phone. 2-IN-1 INSTALLATION Most phone holders either attach to an air vent or to the dashboard. However. the 7Tech design allows you to choose between both options. Use the connector screw to fasten the vent or dashboard mounting piece on the back. Then. slide the vent attachment to the car vent or use the 3M adhesive to attach the dash mount. Features2 in 1 Magnetic Car Phone Mount Suitable for Air Vent.
