User Review: MSR DragonFly
A great, reliable, powerful stove. Sure, it is a little loud, and not the lightest, but for me it is worth carrying on a long trip just because of the convenience.
I also found that is uses very little fuel compared to what I would expect. I went on a trip with 2 full bottles, wanting to be safe, and came back with 1 and a half after 6 days or so just boiling water.
One remarkable thing about the Dragonfly is that the design has been almost the same for over 15 years, so for my old Dragonfly I can still go to the store and buy another fuel pump the day before I am supposed to leave because my old one breaks in a test. MSR is great.
