Brunton Flex Foldable Canister Stove

The light weight and larger flame ring of the FLEX sold me. I got the Brunton FLEX , made by Optimus, over the Optimus CRUX because the FLEX had 4 pot supports and reports that it was a snugger, non-wobble fit when unfolded for cooking than the CRUX version.

It's a great stove for having a more diffused heat that avoids hot spots. I put a very thin film of synthetic motor oil on the sliding collar shaft to prevent wear and keep the tight fit. Synthetic oil has a very high heat tolerance.

This burner weighs only 0.7 oz. more than my very light Vargo Jet-Ti burner. If you cook - not just boil water - with titanium pots you NEED this stove to avoid hot spots and burning food. Personally I feel titanium is way overrated. Just sayin'...

This is a great stove. In boiling competitions with a Jetboil, it has boiled water in about the same time. And the Flex has a wide flame and simmer function to be successful in cooking for a larger group where the Jetboil would fail. It is very small, very light, and has not shown any signs of wear. Definitely a good purchase.

The Flex is small, light, simple and efficient. I just got rid of my higher priced Optimus Nova multi-fuel, as a result of poor performance. The Flex is my new primary backpacking stove and serves my purpose even at higher altitudes. Hasn't failed me yet as the multifuels have as they are too "fussy". If I used any liquid fuel it will be my old SVEA 123 or homemade alcohol. Remember to keep it simple. The Flex folds up and tucks away in a pouch that comes with it that attaches to the bottom of the fuel canister.

For the size of this stove it is amazing. It's small and hardly weighs anything. It will boil water fast, up the side of a mountain in a blizzard it is a lifesaver. Backpacking where weight is an issue, this stove is awesome.
