Ran the UTV version on my Maverick all last year. Works great on the SxS. Can really help with belt life and let you know when you're in the danger range for belt temp.
Didn't know they made a snow version till now, though I think it may be a little harder to monitor on the sled.
Clutch temps on a Doo would be too scary to monitor lol
As long as you run your clutch cover you're golden
