The Baseus Metal Age 3 (BS-CM028) in Cluster Black is a gravity-based car phone holder designed for secure attachment to your vehicle's air vent. It utilizes gravity linkage technology, which means the side arms automatically clamp down on your device simply from the weight of the phone, allowing you to place or remove your phone with a single hand while driving. Constructed from a combination of aluminum alloy, ABS, and PC, the mount weighs 90 g and measures 100 x 98 x 48 mm. To ensure a stable fit regardless of your car's interior, it features a hidden tail hook that expands via rotation and an adjustable supporting gasket that adapts to different fan blade shapes. This combination of materials and design makes it a practical, sturdy, and low-profile mounting solution in a sleek black finish.
