Double Garage Parking Aid-Parking Ball Guide System, Parking Assistant kit Includes a retracting Ball Sensor Assist Solution.A Perfect Garage Parking Indicator

Reduced all parking stress putting both vehicles in the garage. My truck tested my skills, but these took all the guess work out. Easy to install.

We set these up for our 2 cars very easily. The feed-through clips they give you to hold the string in place are good, but I can see how walking into the ball by mistake when the car isn't in the garage could cause the string to slide in the clip and change the height of the ball. After reading other reviews, and once we were happy with how the balls were positioned, I put some tape around the clip to hold the string in place. It's been less than a week but we've already disturbed the balls a few times and both stayed in place, so we're confident that's not going to be a problem. It's a pleasure not to have to get back in the car, restart it and move forward a few inches because you didn't come far enough into the garage! Really fast delivery too. We're very happy with the purchase.
