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.
- Compatible with all MSR 1.5L and 2L pots (with the exception of the Titan 1.5 L)
- When used with liquid fuel stoves, or those like the WindPro™ stove with remote burners, it acts as a wind block by extending below the pot

- "Lightweight but Bulky"
So this heat exchanger does what it's supposed to do and it's lightweight, which is great, but the issue is its size. It's very bulky and it doesn't pack in small. If you don't mind hanging it on the outside of your bag then you're fine. It probably helps your pot/pan heat up faster especially in the cold or wind, but to me it's more of something that's nice, not necessary, to me it's more of a hassle than a convenience. Personally I give it a 3 star for backpacking but a 4 star for car camping.
