Suction cup phone holder is designed to ensure that no marks are left behind when it is removed, this is because we use a special material suction cup which fits well on different types of dashboards or windshields and does not cause any damage to the surface.
In contrast, many other brands of phone mounts leave some nasty marks when removed and need to be removed with cleaners or other methods. Not only is this a waste of time and effort, but it can also cause permanent damage to the interior of your vehicle.
