They worked as suggested. Seems kind of flimsy, but they somehow work. If they didn't come with the jack and stands that i bought, i probably wouldn't have bought the chocks seperately. My good old piece of 4x4 will stand guard as backup.

Two chocks are connected with a black screw like fastener that is nearly impossible to remove. They are light weight and made of plastic. Don't know if they will be strong enough to hold my car; I guess I will know when it falls on me. The label says to use "2 chocks on one tire." Go figure that one out. Chocks are made in USA, so cheap plasticky things are not exclusively made in China.

My Truck was on a slight hill, and I put these chocks under a wheel to keep it from rolling. It rolled right over the chock and crushed it. Cheap thin plastic. But it's not horrible for $5. I only got them to raise the price on my order over $25 so I could get free shipping! I'm now using these for my pop up trailer which weighs next to nothing and they work great!

Secures a light car by chocking the wheels. Pros: Lightweight, small, stacks together Cons: Alittle too lightweight, hollow, possibly bordering on flimsy. Would be great if the plastic/polycarbonate material was thicker or more filled for sturdiness and heft.

Perfect for my small travel trailer and they don't take up too much space. Orange color is key for not leaving them behind.
