Fasmov 2 Pack Solid Rubber Heavy Duty Wheel Chock, Premium Chock for Car, Travel Trailers, RV, Truck, and ATV

good quality and heavy duty. Bought to use for my sons chevy silverado (about 5k lbs), that isn't running, as we had to push it from one part of the yard to the other, but struggled to get it out of a little dip in the grass where it sunk in a little after the rain. We did not have another vehicle to pull it out and didn't want to pay too much to get it moved. Each time we rocked the truck a little, making a little space between where the tire was sitting in the little sunken dip, we would shove one under a tire and then do the same over, shoving one under the other tire. Getting it out of the dip was a pain, but these really helped to stop it from falling back into that little dip.

No roll

Muy bueno y buen material

These are slightly small chocks but effective for sedans and smaller cars and for small trailers. If the tires you're chocking are maybe 36" or more in diameter, these might be a little small for safety, and I wouldn't rely on them on any serious slope. But if you want to chock a typical car while you have one end jacked up, these work just fine. They're heavy-duty and easy to store compared to larger chocks, although they don't nest at all, or anything. They're non-slip enough to stay put adequately on a smooth concrete floor.

They are raw rubber, work great, but smell to high heavens (tar smell) leave them outside to cure, smell is dissipating slowly

I bought these in order to safely conduct oil changes and other minor car repairs that require me to get under the vehicle - I ended up opting for these over less expensive brands because of the "Heavy Duty Rubber" construction (figured plastic ones would slip on my epoxy-sealed garage floor) - and let me tell you, boy do they work. I forgot to remove them when I was done with my girlfriend's oil change, and when she went to back out of the garage the car wouldn't move. Seriously solid construction, I feel very safe working under my cars with them. I ended up buying 4, as I like to chock the front and back of both wheels on the ground during oil changes - might be overkill, but it might save me some early funeral costs I suppose.The ONLY thing that I dislike about these is that they stink to high hell! I have these stored in my garage within a storage cabinet - my entire garage has a faint rubber smell, and the storage cabinet smells like it's made entirely of rubber. I'm sure this will dissipate over time, but dang do they smell!As long as you store them outside, you cannot go wrong with these. Don't hesitate, just go ahead and get them now.EDIT: After about 2-3 weeks of sitting in my storage cabinet, the strong odors have finally started to dissipate. I thought that this would take longer due to the intense odors, but the scent is barely noticeable now. Great product!!!

They work as they are intended to do

They’re wheel chucks that get the job done. But they STINK! They gave a very very strong odor that’s almost unbearable.
