These were more heavy duty than I expected. They do have a smell as others have reported, which is not unexpected. Left mine out side for two weeks (unexpectedly) and the smell is mostly gone. So I'd say if the rubber smell will bother you in an enclosed garage, open the box and let them air out for a few days.

Great product. It looks very solid and high quality. We use it to fit our minivan and SUV in the driveway. I bought some 8" lag screws from Home Depot, drilled through the asphalt, and tightened the screws. The included screws are good for concrete only.

Heavy duty and came with screws to secure to concrete. Stops my car well.

Very useful. They are quite heavy which is nice.

I’m using it in my garage. I didn’t have to use the fixations. It stays in place.

Helps me to park perfectly in my garage. No need to go back and forth to ensure enough space in front or to ensure garage door wont fall on my back bumper anymore. Like others have said before the smell is very strong and seems to lasts forever
