Rating: rated 4 of 5 stars

I have had the opportunity to use the Helios on a few trips now. While heavier than most cylinder, it is extremely useful for guiding groups of 3-6 people. I have used it for car camping in Joshua Tree, backpacking in the Green Mountains of Vermont, and, most recently, a winter training backpacking in the Adirondacks.

That was the stove's only downfall. As might be expected, performance at sub-freezing temperatures was mediocre at best. Even with the fuel stored warmed inside a belay parka, and chemical heat packs insulated against the fuel canister with ensolite foam, the melting / boiling times were extremely slow (12-15 minutes) to melt enough snow for 1 liter of water brought not quite to a boil, compared to 6-7 minutes with an MSR XGK.

The simmering ability in 3 seasons is great, the fuel efficiency and speed are great.

Overall - A great 3 season guiding stove, but not so in winter.
