The instructions are how to parallel park.......but everybody needs a pointer on their dash, right? Some great marketing right there.
It looks like you place the pointer on the dash at an angle, with your car parallel to the car in front of the place you want to park into and you back up turning the wheel until the pointer is parallel to the curb then turn the wheel to the other side. A completely useless gadget.
When we were kids, my buddy sent $5 away for something guaranteed to make your "junk" double in size. He had seen the ad in a Police Gazette magazine at the barbershop... I saw him last week and asked him if he still had that magnifying glass.
