excellent video. i have a cold use stove comparison out this week so will link to this too.

Great video ...i do pretty much the same but put the hand warmer in my trail shoe or mid under the gas cartridge after i have wiped the condensation off...i dont like faffing about with alcohol stoves and by the time you have added a windshield a jet lighter plus a heat proof cloth to protect your footprint theres not much weight difference or advantage to justify not taking a gas stove plus you dont have to wait for ages or expose yourself to more tent fire risk...Gas is number one in my opinion.

Wish we had that fuel in the US.
