Works really well. Coming home last night my drive way was coated with a nasty black ice...bad enough that the LC slid 10 feet backwards (fairly steep incline) with my foot on the brake, and I could not stand on the ice without siding down my driveway. I first tried starting in 2nd gear and locking in low...no forward movement at all. Engaged the crawl control and up the driveway she went, albeit making all kinds noises.
