Has anyone ever used any of these traction devices in the snow. I'm sick of getting stuck down my sloped driveway. Some look better than others, any suggestions?

they will all work but it will suck to get out everytime you go home to throw them out

They should work but if your high centered on your frame or diffs they will be useless.

Funny story, I got stuck in the snow and tried using the traction ramps, when spinning my tires the ramp was tearing bits and pieces of the tire. After looking at the picture I just figured out I had the teeth pointing up. Doh!

And now they didn't help get me out cause my diffs where buried in the snow. Had to get a little tug. Personally I wouldn't waste my money. I'd save it for a locker or lift if you don't have 'em.
