Using the Quad Lock MAG Universal Adaptor is easy. First, find a flat surface on your phone, case, or other flat metal or plastic item. Clean the surface well to ensure a good stick. Then, peel off the adhesive on the adaptor and firmly press it onto the surface. When you want to mount your phone, simply bring it close to a compatible Quad Lock MAG™ standard head or Quad Lock® Twist, Lock mount, and the magnets will pull it into place. As for maintenance, keep the adaptor clean. You can use a soft, dry cloth to wipe it down. Avoid using harsh chemicals as they might damage the adhesive or the adaptor. If you notice the adhesive losing its stickiness, you may need to replace the adaptor for a better hold.
