1. Please use the holder on hard, flat surfaces only. Avoid uneven, cracked, curved, or soft leather surfaces. If the surface depresses when pressed by hand, do not use it—examples include soft sofas, car seats, etc. 2. To prevent loss of stickiness, do not leave the suction cup exposed to air for extended periods. When not in use, cover the suction cup with the included round paper or attach it to another flat surface. If needed, rinse the suction cup with water and let it air dry to restore its stickiness. (Do not wipe the suction cup with paper towels or other materials, or dry it using high heat.) 3. For new holders: Avoid using directly on car screens initially, as the suction cup's extreme stickiness may make removal difficult. We recommend using the holder on other surfaces first to slightly reduce its initial stickiness before applying it to a car screen. 4. The nano adhesive on the suction cup alone cannot secure the holder. Rotate the swivel ring clockwise to its maximum position to lock the holder in place. To release, rotate the ring counterclockwise and use the two protruding release tabs to detach the holder. [Complete Articulating Movement]: Engineered for ultimate flexibility, this vacuum absorption magnetic bracket features a base that rotates a full 360° and dual-axis arms that fold through a 210° arc. This allows you to precisely position your phone for the perfect view. Switching from portrait to landscape orientation is quick and intuitive, making it ideal for both automotive and office use. Its innovative folding mechanism shrinks the car phone mount by half for compact storage, maintaining a clutter-free environment. Rigorously tested over 5000 times, it guarantees lasting stability and dependable performance. [Powerful Suction, Rock-Solid Hold]: This vacuum magnetic phone holder features a 4-layer high-strength nano gel suction cup with rotating vacuum-lock technology, supporting up to 108 lbs (49 kg) and gripping firmly through extreme temperatures (-40°F to 300°F). After 9,999+ durability tests and 300+ reattachments, just rinse the cup with water, let it air dry, and it regains ~99% of its suction power—back to like-new stability. (Please do not dry with paper towels.) Especially, This car mount has two larger tabs, giving your fingers plenty of room to grip it touching or damaging the nano gel suction cup. [Stronger Grip, Smarter Hold]: With 24 high-performance N55 magnets, this suction cup phone mount delivers 320% stronger magnetic force than basic mounts, generating up to 3,200 GF of magnetic power—enough to hold 60 phones. It passed 8,000+ vibration tests and extreme road simulations, keeping your phone secure even on bumpy roads, during sudden stops, or sharp turns. The precision magnetic array ensures zero signal interference for seamless navigation and crystal-clear calls. [Broad Compatibility]: This magsafe car mount is designed for iPhone 12-17 series and all MagSafe devices. It includes 2 metal rings to deliver the same strong hold for non-MagSafe smartphones from 4.7 to 7in. How to apply the metal ring: Attach it to the outside back of your phone case or directly to your bare phone—never between the phone and case, as this weakens magnetic strength. Just a heads up: The magnetic ring won't work with phone cases that have built-in finger rings, armor/leather/suede materials, card slots, or any uneven back surfaces. [Not just a phone holder for your car]:This magnetic phone mount works anywhere in your car with a flat surface—windshield, panel, dashboard, mirror. Its compact foldable design lets you use it beyond the car: hit the gym, cook hands-free, desk-mode at work, even on planes or high-speed trains. A must-have for content creators and live streamers who need stability anywhere.
