On Sunday i tried my Autosocks for the first time and was amazed at the difference it made. Normally the car would have stayed safely on the drive when it snowed, but i was away and had to get home. There was about two to three inches of snow and the car wouldn't move from the position it was parked in (on a very slight slope). So a put the Autosocks on the rears and the car was moving as though there was no snow, next a short but steep hill to get onto the road, i didn't need to take a run at it, the car just made it to the top problem (to the amazement of my dad)
i then had 6 miles to the motorway on snow all the way, doing 20-25mph the car felt under control (no squirming about). Once at the motorway where i could see tarmac, i pulled the off and i was away again.
They were quick to put on and take off less than 5 minutes and as away keeping going when the conditions got difficult i think they are great. They are quite expensive especially if you buy front and rears, but the biggest problem i've had with my is200 in these conditions is poor rear traction so you could probably get away with them just on the rears.
Once home i dried them out, they were a little dirty, but there were no signs of wear
Only thing i'll change are the gauntlets they supply, as i found they weren't quite long enough and ended up rubbing my sleeves on the arches (minor issue)
Hope this helps may be a little late for this year, but i thought i wouldn't use them when they arrived after the snow in January, so who knows
