The Aduro magnet phone holder features six strong magnets that will safely hold your phone preventing it from swaying or falling. Made with a highquality rubber construction base so it will tightly grip to your car vents without slipping while taking turns going up and down hills or braking. The rotational ball head enables you to adjust your phone in any viewing direction angle. Simply attach the included 3M adhesive metal plates directly to the back of your device or insert them on the inner side of your phone case. Use both plates for extra heavy devices to keep your device mounted on the phone holder mount magnetic. The reinforced dualsized claw allows a perfect fit for most car air vents even with a case on it.
