Must admit my girlfriend had them fitted to one of her bikes and they are a god send, I have fitted them to every bike I use to get into work with, I do 24 miles each way and during the winter they make such a difference, I also use Oxford muffs this keep the heat in even better, they now get so hot I have to take my hand out to cool them down, the oxford heated grips are the only ones I ahve tried the 07 and the new 08 models, the 08 I think have a less useful switch just 2 button to increase the heat and reduce while the old one was a push button and then worked a bike like a volumn swtch (much better) but either way I'd rather be called an old woman by a biker who is unable to open his hands due to cold fingers, than not have them.
