First tried in 3 inches of snow, didn't even go 20 feet and the first one broke and my car skidded. I tried to start again and the 2nd broke down immediately. Tried to remove them and two are completely stuck. It took longer to remove them than they were in the car. DON'T SPEND YOUR MONEY! I was looking for an easy to install alternative to cable chains but instead my car ended up in a ditch and wasted. I can't even return them because the return period has passed by a month. I had to trust my intuition and never try a useless product.
