Review on 🚗 Retractable Ball Parking Aid - Genie Yellow Perfect Stop Compatible with All Garage Door Openers-GPS-R, one Size by Ryan Bennett

This is a tennis ball on a rope with metal grommets that allow us to attach the rope to the garage door in such a way that the ball only slides down when the garage door is open. If we are following the instructions correctly, we should start by determining the first eyelet when the car is parked in the garage and then use that spot to determine the length of the rope. It's difficult because the first position will be directly above the car. You have to either climb onto the car's roof or move the car sideways and do it by trial and error. When I saw that my son had the keys to the car and wasn't home, I quickly realized that just hanging the ball on one side of the windshield and letting go was more effort than worth. It's okay if I bump into the ball once in a while when the garage is empty. Of course, I'm pretty sure that if I hung it as intended, it would work as it should and would climb to the side if I didn't. need this
