I used the heated stuff this morning on the way to work. 42F on the V-Gauge. I have the Gerbing jacket liner and overpants, as well as a couple types of gloves. I mounted the thermostat in my horn cover.
A couple of observations:
1.) The glove liners should be worn reversed to what they say. This puts the wires on the outside, instead of under your hand against the grip. Also, the liners can be put on, plugged into the liner, the wires tucked away, before you put on the jacket. They leave enough hand mobility that you can still fasten helmet, turn on X-M radio, etc, before you put on outer gloves.
2.) If you have engine guard chaps, you don't need to plug in the pants. There is enough heat coming back from the radiator to keep your feet toasty, down to about 35F.
3.) Get some Zook for your glasses. My (new - thanks Okie) Schuberth helmet visor doesn't fog up but my glasses do. An application of Zook takes care of that.
4.) The indicated voltage on the V-Rod drops from 13.9 to 13.7 when I run the system. No problem there.
