I bought this a few years ago and left it in the car unused until last weekend when a big storm blanketed the Sierras in snow and chains were a must - so I have got her out. Installation was incredibly easy - Tesla's suspension was raised, placed on top of each wheel, moved forward a few feet, and the installation completed around each wheel. The whole process only took a few minutes and was much easier than chains. They held up securely for the 30-40 miles I rode in the snow, mostly at 30 mph. Removal was also easy afterwards. Although a bit worn, they look good for at least one more use. While they don't look reliable enough for regular use, they are ideal as a backup or emergency option. Highly recommended.
