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.

Heavy enough to easily block even a larger car.

Super produit. Ils sont lourd et dans mon cas, je n'ai pas besoin des les fixer avec les vis.

Awesome wheel stoppers. Firm and heavy.

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

Very useful. They are quite heavy which is nice.
