2 Pcs 18'' Heavy Duty Parking Aid for Garage, Parking Gadgets Protects Car and Garage Walls, Parking Stopper Easy to Install 2 Packs

Very easy to install. Make sure you clean the floor or surface in which you are installing. I installed on concrete for a backstop on my two vehicles in my garage. I’ve been using them for several months now and have had zero issues. I often back my car into them and over them.

I wanted a way to park my car in the same spot in the garage every time so the door is very close to the back of the car allowing room in front of it to walk by without the fear of scratching it and it works great. Cleaned floor before pealing and sticking it to floor and is holding tight. Used one for my car and the other for wife's. No more second guessing if your in the perfect spot. Update After a couple of weeks and a couple of wet road conditions the included peel and stick backing is not water proof and releases from the water running off the car and tires. My solution was Gorilla Tape. If they provided a stronger/waterproof adhesive solution this would be the Perfect Product.

These are really sturdy and great quality! Easy to stick down on floor, and makes parking a huge vehicle so much easier! Forget the tennis ball! 🎾

Working well but adhesive does not seem to be holding firm. Pressure from car tire bumping it is causing it to move forward

These are so easy to install, and made it super easy for me to park in my garage. I now know when I'm in far enough in my garage for the door to go down. LOVE THEM!!! And they were so easy to put in! I bought a second set for my husband's car.

I bought this product to have a stopping point in my garage. The reason I give it 3 stars because the adhesive didn’t hold up, and one of the blocks is completely destroyed after a year and a half of use. I guess it couldn’t hold up to my truck tires. Given the price point I suppose it’s not that bad.

These are fantastic..... Finally got rid of my waffle ball in the garage ceiling

UPDATED Review(previous below): My wife and I bought a new car. We baby it. And our garage is a bit narrow so when we pull in, it is slow. Because our garage is so short, we barely have room for the garage door to close, so we slowly approach the stops until we feel them bump up against the stops. They are equal distance from the front wall, carefully measured out when installed so the tires touch at the same time. The floor was clean and dry when installed per instructions. I explained that so you know my wife doesn't race in and slam into the stops! And they were not applied to a dirty surface. The adhesive failed on one of the stops and tire was able to push it forward even though barely bumped into it. Great concept, but poor performance. Cannot recommend it. Ignore review that follows that I posted originally. _____ previous review: These are the right height to let you know when to stop to allow garage door to come down. I have seen some advertising taller units, but unless you zoom into the garage requiring a 'barrier', you shouldn't need that! They were easy to put in place, and the shape/height is such that you don't trip over them when car is not in the garage. If they stick long term, will give them 5* rating.
