Here is the posted ad for the Blinder for sale:
I am selling a New in Box - Blinder Laser Jammer, made in EU - Model #: M-06 HP.
It is designed to block lasers aimed at the vehicle. It consists of two small black boxes to block the laser that are installed behind the front and rear bumpers. I bought it a few years ago to use in my sports car, never installed the unit & recently sold the car.
