Car Parking Stopper – 2PCs Heavy Duty Rubber Curb Car Stop for Garage and Driveway, Parking Aid, 18” Tire Wheel Stop for Cars, Vans, Trucks – Prevents Hitting Wall or Barrier – Easy Installation

These are heavy-duty and work perfectly in my outside parking space. i used the adhesive but you could probably get away without using it (for example inside a garage) as they stay put when your tires touch them backing up. The yellow reflector tape isn't the best quality so I replaced it with my own reflective tape.

stops the cars from hitting the wall as intended no issues now

It is as it states. The mounting hardwate looks tops but I'm using them without the hardware and they stay in place just fine!

These stoppers have worked great in our garage for when to know to stop pulling forward. We have a large suv and truck and they work well with both. I like them better than hanging a ball from the ceiling.

great product, met my needs for parking my golf cart in my patio.

Works great

I was expecting something similar quality, rubber stoppers that I have from other brand, but they are plastic, and deformed the first time I stopped my car over them. I couldnt buy that brand cause of the size, they are too big for my current need, so I only found these ones

Enviro-Nightmare Packaging. These are heavy molded bricks that don’t require a sealed bubble wrap package, that is placed inside a box.My package didn’t have the adhesive, but happily I don’t need it. These work fine just set on the floor without being attached.
