The Dragonfly is an excellent stove! The fuel bottle is refillable and you can buy white gas by the gallon, so it’s economical. Works well at both high altitudes and in low temperatures.If you want a small highly versatile stove that can boil water fast and and be adjusted down to do a butter sauce The MSR dragon fly is a great stove, it is a white gas stove that packs up very small. The fuel bottle can be up to a liter. The down side is you need to prime.
I have an old MSR Superfly. It runs on iso-pro fuel, so I have to purchase/dispose of canisters, but it packs tiny, has a good sized burner and has been reliable for over 10 years of backpacking/camping. I use it when flying to locations; when driving, I use my Camp Chef Everest and the Superfly is my backup stove.
