Came across this product, go claws, which is a tire chain alternative which are street legal, thereby providing traction in snow.
Has anyone heard of or had experience with these?

Here is an exerpt from their site:
How it works?
The unique patented Flex-Trax, Advanced Traction System is composed of tread faced mud/snow elements, that can be quickly and easily secured to a vehicles drive tires. The product combines proven techniques of mechanical engineering, physics, material handling, and hydraulics to achieve a modular design that gives superior performance compared to mud/snow tires and tire chains.
Previous tire tread designs for adverse conditions have included beefy lug members (knobbies) or protuberances extending outwardly to bite into the mud and mud. In operation, the grooves that form these extensions become filled with fluid solids to the height of the extensions, rendering the footprint profile innefective for traction.
Flex-Trax solves this problem by using the opposite approach. Pascal chambers are utilized, instead of bulky lug member extensions. Pascal, and eighteenth century physicist, was the first to use hydraulic pressure to achieve a mechanical advantage
