Using the Quadlock Desk Mount is easy. First, clean the surface of your desk where you want to place the mount. Then, press the re - usable nano suction base firmly onto the desk to secure it. Attach your smartphone that has a Quad Lock case to the mount using the Quad Lock mounting system. You can adjust the gimbal head to get the best viewing angle for your needs. To switch between portrait and landscape, just give your phone a gentle turn. When you're done using it, you can easily detach your phone from the mount. For maintenance, keep the nano suction base clean. If it loses its stickiness, you can wash it with mild soap and water, then let it dry completely before using it again. Avoid exposing the mount to extreme temperatures or rough handling to ensure its long - term performance.
