The Heat Exchanger increases the efficiency of your stoves up to 25%. The unique waffled design channels the heat from the stove up the sides of the pot to increase the heated surface area. When used with liquid fuel stoves, or remote-burner canister stoves like the MSR WindPro™ II, it can also act as a wind block because it extends below the pot. WARNING: Contains brass that can expose you to lead, a chemical known to the State of California to cause cancer, and birth defects or other reproductive harm. Learn more about Prop 65
