[Enhanced Vacuum Suction Cup, Enhanced Manual Rotation] This foldable magnetic car mount features enhanced vacuum suction and a rotating locking mechanism for ultimate physical suction power. Unlike conventional fixed mounts, this magnetic car mount has a quick-release design for easy repositioning without leaving any residue. The more violent your driving, the stronger the suction. It is the ideal magnetic phone mount for your car. Important tips: Use the included adhesive pad on smooth but textured surfaces to ensure a secure fit. Avoid mounting on uneven surfaces. For non-magnetic phones and cases, use the included magnetic ring. It is not recommended to use the adhesive pad on uneven car dashboards. To check the surface smoothness without the adhesive pad: Draw a circle with your fingernail. If the surface feels smooth and makes no sound, it is suitable for mounting without the adhesive pad. [Adhesive pad included for flat but textured surfaces] This car mount is also suitable for vinyl dashboards. It works best on windshields, glass doors, ceramic tiles, acrylic surfaces, polished metal, stainless steel, aluminum, chrome, and smooth painted walls (especially those with a glossy or semi-gloss finish). This handheld car phone holder is also suitable for polished marble or granite surfaces (such as countertops), as well as smooth, polished, or sealed wood and other plastic surfaces.
