The No Blind Spot Rear View Mirror.
This is the rear view mirror used by police officers and professional racecar drivers to eliminate blind spots. The patented, seamless mirror has a 180-degree field of view (standard mirrors offer only 52 degrees) that provides a distortion-free reflection of rear traffic across an entire five-lane highway, and it allows continuous monitoring of adjacent vehicles from the moment they begin to pass until they are visible in your peripheral vision.
The mirror automatically reduces the headlight glare of trailing vehicles by 50%, clamps to your existing rear view mirror without requiring the use of tools or adhesives, and is entirely shatterproof. 15-3/4" W x 2-3/4" H x 3/4" D. (10 oz.)
