Finally an extension mirror that can be installed in seconds! The suck-it-and-see mirror combines convenience with safety and can be adjusted from inside the car using the cars own mirror adjusters. Designed to be aerodynamically stable ensuring low vibrations. To install, place the unit against your vehicle mirror, apply a little pressure then rotate the knob until the unit is firmly attached. Then simply adjust your mirror as normal. Comes complete with a safety cord for peace of mind (although this product is tested to 120mph).
