I love this stove! I have used it for several years in the high mountains (8,000 to 14,000 ft) of Colorado and New Mexico. It simmers like a gem when needed and absolutely cranks if you want to melt snow or boil water. It is a bit loud, but I have always liked that, as it announces to the wildlife (bears) that man has arrived. Match this with the lightweight stove stand made by UCO and you have the best stove in the world. I own seven (I sell backpacking equipment for a living) of the top backpacking stoves in the world and the DragonFly is my top choice. My Optimus Nova is a close second, and maybe my top choice on an international trip due to the fact that you do not have to change the jets (you do on the DragonFly) when switching between kerosene and white gas. One last thing, all types of replacement parts and maintenance equipment are readily available for the DragonFly at any decent backpacking store, so upkeep is a breeze.
