I used the Autosock for the first time last week and was VERY impressed with its performance. I was done, and at about the same time another motorist, who had already jacked up his car when I pulled up behind him, put on his first chains. In the next few days I drove through the city and the people in the city were amazed and asked questions about the product. I then ordered another set for the second machine. I'm really impressed with this product and how it holds up to abuse that seasonal chains can't.
