Yeah, me too. I got mine as I ave a few bikes and it's really easy to change them for one to another. I'm the world's worst mechanic and it only takes me 10 minutes tops - of course I don't route them very tidily, given that they'll always be temporary on any gven bike. My only complaint is that there is no adjustability other than your speed and the temperature.
I find them particularly good during Autumn and Winter months, when I use latex workshop gloves inside my summer leather gloves. That way, I keep dry hands (the latex inners) and maintain good feel. The heated outer grips keep the hands warm and help dry the leather gloves. In short, they're very versatile.
