I laughed out loud when I received them. Keep them to give as gag gifts. These traction devices are useless off-road. The connecting pins are thin and bend easily under the vehicle. Plastic has very little grip on the road for tires to snag on. It immediately clogs with snow or mud. The 7/16 inch hard plastic case doesn't last long before it breaks. save your money I do not recommend. Even a small amount.
