I'm looking at the Oxford Heaterz Premium Cruiser Heated Grips that come with a temp controller and wonder if anyone actually uses the controller. They get great reviews but I suspect that most people set them up at some temp that works for them and never adjust beyond that. If I don't need that controller as I suspect then I may opt for a unit without one so I don't have something on the handle bars I never use. I'd love to hear from users about this - do you use the controller as ambient air temps fluctuate? Also if there's another brand/model people recommend please chime in.
