Review on Set Of 2 HIGOOD Rubber Wheel Chocks With Convenient Handle For Car Safety – Sturdy And Resilient Design, 8" X 4" X 6 by Marc Sortijas

I imagine these will be durable - they are heavy for their size - but I can't say for sure. I spent several days under a car using these, and honestly I would have felt a bit safer if they were simply bigger. At less than 4" wide these were dwarfed by my car tires. I felt safer using 4" high concrete blocks behind my tires. And I have no idea who designed the "handles." I have average size hands I think, and I can't slip any of my fingers in these tiny things. They are useless. These are definitely better than nothing, but there are probably safer choices that are easier to use.
