The Magnetic Patient Caution Driving Vehicles magnet is a life-saver. I appreciate the convenience of having it be magnetically attached to my car so I can easily switch it between vehicles .It’s a great reminder to other drivers to be cautious whenever they see it on my Automotive. My only concern is how well the magnet will hold up in extreme weather conditions, but so far it has been fine. overall, a great product that I would highly recommend to others..
