MSR Heat Exchanger

I purchased one of these and was thinking it was going to be great to use instead of the clumsy aluminum that comes with MSR stoves. I went out to the garage and pulled out my different pots. This one is too big and so is this one.. Etc.. Etc.. I finally get down to my itsy bitsy pots and it finally wraps around them. I ended up getting a Reactor stove in the 1.7L and I just use that to crank out melting and boiling water when trying to pack light. I think it is a toss up whether to get one of these or not. I do like it when I have used it, I just wish they had a larger size option. The bigger the pot, the more liquid or snow needing to be efficiently heated.

works great, have used it with a few different pots and seems to work better than without it. not sure how much faster or better it is, but it does work.

i've used this on all my trips except for the most ultra light summer backpacking trips. it does a great job of heating teh sides of the pot, and saving valueable heat from escaping into the wild blue yonder. in cold temps, it aids boiling time, and i'm always boiled up faster than my buddies who don't use the exchanger. it's heavy, but can offset its own weight over long trips due to saved fuel. this is especially true in mountaineering/alpine trips where temps can be very cold. i'd give it 5 stars, but it is a bit heavy... sidenote, mine is litterally 16 years old, and looks brand new. well made and very durable.
