How does it compare with a Jetboil Flash?

The WindBurner's regulator and deep wind-blocking burner hold up better in gusts and cold. The Jetboil is usually cheaper and its pot is easier to find accessories for.

How fast does it boil water?

About 4.5 minutes for 1 liter with MSR IsoPro. Expect longer in cold water or with a partly empty canister.

What fuel does it take?

Standard canister fuel such as MSR IsoPro. The regulator works best with isobutane-propane mixes; the 100 g canister fits inside the pot.

The burner with folding legs, the 1-liter hard-anodized pot with lid, and a stuff sack. Fuel is sold separately.

Is the WindBurner worth it?

If you camp in wind or cold and mostly boil water for one, the steady regulated flame justifies it. If you cook real meals or camp in calm weather, a cheaper open burner does the same job.

Does it work in cold weather?

Yes, better than most canister stoves. The regulator keeps output steady as the canister chills, though a cold or nearly empty canister still slows the boil.
