With winter around the corner, I upgraded from my $4.99 Chinese super special heated grips to these:

Suitably impressed, they put out some great heat. Very easy install once I cleaned up the left over adhesive from the cheap warmers. In fact the left over stickiness meant I needed no further glue.
I went the adventure size, and they fit snuggly with very little to trim off the ends.
Relays not required (direct connect to battery) as the unit automatically shuts off after bike stops.
No more cold fingers, bring on winter!
