Oh,yeah, thought I'd "relay" my recent experience. We've had several mornings in the 20's here. The new thirty something watt glove liners are pretty much overkill.
Half volume on the Heat-Troller is HOT and they heat up quick - much quicker then my earlier gloves. I used the two loops of nichrome mainly for redundancy anyway - in case a wire breaks I'll still have 1/2 power. I did have to move some of the wires away from my knuckles where they caused a little discomfort. All fine now.
Love the fan concroller idea!
Keep us posted. I originally used a 12v light dimmer from an RV dealer and before it died it actually increased the heat setting on its own!
I could watch the knob actually turn itself to the right. I gave up and bought a Warm N Safe unit.
