Anyone used trac grabbers?

There are various vids on youtube about them but they don't seem to be commonplace in typical recovery equipment. I'm wondering if they would have helped me get unstuck from the mud last time I was stuck....

Logically they must work. Ghee they would be messy to put on once you are bogged though. If you are in it digging holes then I'd give them a crack if they were there. To be honest I'd probably pull my winch ripe out way way before using them though.
