Ultra Strong Magnet, 100% Drop Proof: The MRGLAS magsafe car vent mount uses upgraded 40*N52 magnets to securely support up to 3kg of cell phone (equivalent to 17 iPhone 15s), ensuring stability over bumps, sharp turns, and hard braking. It installs in just 0.1s, and its enclosed magnetic field won't interfere with cell phone signals, navigation, or other functions. Enhanced Air Vent Hook Design: This magsafe car mount has a unique metal double hook to prevent it from falling off easily. It evenly distributes pressure to protect air vents from damage, extends up to 30mm, and fits most horizontal and vertical air vents. ⚠ Note: Our magnetic phone holder isn't compatible with air vents that have curved blades. Improved Heat Dissipation:MRGLAS improves the cooling of this magsafe car mount in two key ways: 1.the upgraded telescopic arm ensures it won't obstruct car vents. 2. the hollow round holes at the back help dissipate heat more effectively, preventing phone overheating and ensuring phone safety.
