Review on Adjustable Ultralight Backpacking Stove - Bulin Camping Gas Stove Burner With Windproof Design, Portable Propane Stove For Outdoor Hiking And Camping - Choose From 3500W To 18000W Power Options by Zha Rivera

6 stars, baby! It'll do anything from a soft keep warm to a triple blow torch x3 at about 4 inches across, higher than your coffee pot. At times you stand back to avoid the heat. Since it's got the long gas feed line the extreme heat doesn't effect the distant pressure regulator. I use it mostly to very rapidly heat my Lodge pots, ovens, fry-pans. 20 seconds and you're good. Probably too big for day hikers, depends. It's regulator, etc, I can't speak to because mine's set up on propane with a propane to MSR converter, from here on Walmart for 10 bucks, that'll save you mountains of money and changing canisters frequently. If you're on the fence, climb over and get one before all the shipping issues take hold and impact prices further.
