[One-step operation and automatic locking] The phone holder support feet have a locking device. When you push your phone in and press the holder, the clip will lock automatically within 0.1 seconds. [3-in-1 Multi-function] 3-in-1 mount is more convenient to install on car air vents and dashboards and windshields, meeting your multiple needs. Ultra-stable hooks for ventilation and new strong suction cups (PVC) keep your phone from dropping or shaking, even on uneven roads. Don't worry about dropping your phone while driving. [Air Valve Improved Version] With an overload alarm knob, it can protect the car air valve better than other brackets. The new bracket's ultra-stable hook can be extended up to 32mm to accommodate different air valve depths. Not only suitable for horizontal and vertical air valves, but also for mesh air valves. [Improved dashboard and windshield version] The ultra-stable arms of the new mount extend up to a maximum of 142mm, bringing the phone closer to the driver and ensuring you can touch your device more easily. The ball joint design provides 360-degree rotation, making it easier to adjust the stand for the best viewing angle.
