The only problems with the Suzuki heated grips, is the tiny button (I guess my gloves are a bit too big), and the fact that they do not tie into the dash so the dash does not show the heat setting. As simple and plain as the dash is, it is still very clear in direct sunlight, so I'm fine it's not a posh colour TFT thing, just wish it showed the heat levels on the grips like you get with BMW's.
Oh, and re: the Oxford vs r&g, the Oxford are way way hotter and better, but you get the huge control box thing. As long as you can live with the control box, they are the better grips than R&G (and Suzuki) for heat.
