Product Review

Make sure these are placed on a flat clean surface and the magnets are room temperature when attached. Remove them periodically to clean the back of the magnet and the car surface with warm soapy water. Make sure they are completely dry before they are re-attached. Be careful in very cold weather when they are handled as magnets become brittle and in high heat become very pliable.When not in use store them on a flat metal surface like a refrigerator or filing cabinet.
