Multiple Mounting Positions：The car phone mount holder includes an air vent clip and a suction cup that you can mount it on your air vent, windshield or dashboard. 2 types of bases provide different mounting options in different positions, so you can mount your device wherever you want it. Secure Twist-lock Clip: This vent clip features a twist-lock system to adapt to thin or thick air vents. To install the car phone holder to your car's air vent, simply loosen the twist lock, push the clip onto the air vent blade, and then tighten the twist lock to secure. The mount is quite stable and is unlikely to move, even over bumpy roads. Universal Compatibility: The car phone mount fits phones with 4.0-6.8" displays and up to 3.5in/9cm wide, including Galaxy Series, iPhone Series, HTC, Nokia, etc. The bottom foot can be adjusted up and down to secure phones of various sizes. The Quick-release Button enables you to mount and remove your phone with one hand in seconds. Strong and Secure Suction Cup: The TPU vacuum suction cup features sticky gel that ensures a tight hold on flat surfaces to maximize stability. Plus, the 2-step locking lever provides additional mounting support for multiple surfaces - smooth or textured surfaces. If the gel loses its grip, simply wash, dry, and re-attach. No Angle Limit: The car mount has a telescopic arm that can extend from 4.3in/10.8cm to 5.9in/15cm and pivot 260° to reach your desired viewing angle. Also, the 360°rotatable ball joint enables you to swivel your phone for portrait and landscape view. For added convenience, the newly designed arm makes angle adjustment easy and smooth.
