Let me know how you like them. I'm tired of having the Royal Dist. ones breaking, or having your throttle hand way hotter than your clutch hand
I wanted to give the Oxford's a go!

I'm sure there are plenty of reviews of the Oxford Heaterz, but since you asked.....
I've taken short rides on bikes with heated grips, but never had them on any of my bikes. I was worried about extra wires in an already cramped space, and specifically the wires for the throttle side interfering with the brake lever. This is not an issue, in case anyone else was worried. It's easy get the grip lined up how you want it (the instructions recommend one way, and even describe another popular way). The clutch side was a little difficult to slide on - I had to sand the paint off the bar to slide the grip on (they don't have the same flexibility as plain grips. The wiring couldn't be simpler. I wanted to wire it to something controlled by the ignition, but Oxford suggests that's where many problems occur. People connect to a circuit that can't handle the current. Since I will probably clean it all up over the winter (still looking at higher bars as a bigger project), I connected it straight to the battery. There's a control unit that sits near (but not too close to) the battery, so it's under the seat, and from it there's a quick connect to the controls.
I also used the mounting bracket for the control, because it lines up perfectly with the clutch lever bracket. It's a little higher than it needs to be, but there are no clearance issues and it's a handy place for it. One of the best things about the installation, is that you could disconnect that control unit and remove that little bracket if you wanted it gone during the summer months. 5 minute job (have to lift the tank to pull the wire through).
I got the sport grips and they are comfortable, at least with my heavier gloves. I know it's not too cold this morning, but I still appreciated them. A lot. At only 30%, they were warm enough that I shut them off a few times. They hold heat for several minutes afterwards, so cycling them on and off doesn't mean going from hot to cold. I also thought it would be good not to have them running when I was sitting at idle anyway.
Since Oxford recommends not wiring into an existing circuit, I will likely leave them hooked to the battery when I clean up the wiring, but I may wire in a relay from an existing lighting wire. Since it had all been chopped to crap when I got the bike, I've redone the whole tail section and I have one original wire that's unused (licence plate light I think. Yes, I still have a licence plate light). That would mean I wouldn't risk leaving them on. The controller will shut them off, but not until voltage drops to 10-point-something volts.
So I'm ready for the cold - let's just hope for dry weather!
Edit: P.S. I never noticed one hand warmer than the other in my short ride.
