4 Sets Garage Parking Aid Ball Parking Guide System Sensor Assistant Kit, Include 4 Retracting Ball with Rope, 4 Adjustable Clips and 4 Screw Hooks, Garage Car Stop Indicator for Vehicles

This is a very nice product. Just right in all respects IMO. Note very few bad complaints. Very easy to add, see suggestions. 1. Start with the vehicle in the position you will want it to be each time. Make a mark (piece of tape) on the floor for the front tire position. 2. Pass the string end through an adjustment button, make a large loop and pass the end back through the button. No need to be exact. 3. Pick a spot on the ceiling above where you want the ball to hang. I used the ball and string (attached to a stick) to find a spot so the ball would hang in front of the steering wheel, planning for the ball to hit about 1/2 way up the windshield. 4. Remove the vehicle for the installation. 5. Drill a small hole in the ceiling at the correct spot and screw the hook in by hand. 6. Hang the string loop from the hook with the ball roughly adjusted (somewhat too high). 7. Pull the vehicle into the garage the exact desired amount. Use the marked front tire position to check. 8. Then adjust the string with the adjuster button so the ball just touches the windshield.

They are just as described. We like them.

Cheaper than making some myself.

Perfect for anyone garage! Love that these are easy to install. Price is right.

Works as it should. We have a big vehicle and not-so-big garage, so this is a necessity for a short gal like me who has a hard time looking over the hood.

Added these to the garages and now we don't have to guess how far to pull in. The cars alarms go off way before the wall, so this is helpful. Easy to install. Just had to climb on the vehicles to make sure they hit the windshield in the right spot. You can make the heights adjustable so if you change cars in the bays.

Easy to install and pretty good quality for the price.

I only needed one but it comes with four. Perhaps that's because the tether is not "rope" as advertised but elastic rubber band type material. Isn't that going to break over time, or stretch out so as not to be accurate any longer? I needed only one and it works perfectly, lining the car up for both linear and horizontal placement. I just worry what will happen once the elastic string deteriorates *

A must have for tight garage spaces. The rope does not stretch more with time, so the indication remains true

Have not put up yet as I have not recieved the instructions.
