Garage Tennis Ball Parking Aid, Parking Guide System for Car Accessories, Stop Indicator, Parking Assist Ball, Aid-Parking Kit, Garage Car Stopper, Pack of 2

I initially bought more expensive "park stopper" mats which kept slipping. I bought this and it was easy to set up and works great. Just look at the pictures in the listing and it'll be obvious what to do. Sure, it's ultimately two tennis balls, an elastic string and two catches, but for the price, it's nice to have everything all in one ready-to-go package.

Works great if you don’t have a German Shepard.

Works as described. The little hook was devilishly small for my stubby fingers otherwise all good.

Fun image on them and easy to install

Once you get past the tangle they tie the knot in the string to hang the ball, it works well.

Nice color and happy face

I’ve been asking my husband for one of these to hang in our garage to help guide me on when to stop when pulling in. This does the job. It was an easy install, the tennis ball color is bright so I can easily see it when pulling into the garage. My two young sons will occasionally give it a toss as they walk by if my car isn’t in the garage, but luckily it has proven to be durable.

Allows you to set width and depth of car in garage. The depth is adjustable with spring clip. The reason for only 4 starts is you need to buy your own I hooks as the ones that come with are to small, the other is the knots that the strings come tied. It the rubics cube of detangel!
