I have a Kelly Kettle and it's great! Can heat up water in it pretty quickly with small sticks, bark, paper and whatever burns. It's well built. I've used it on rainy and windy days under a tarp or vestibule; you don't have to make an open fire. The fire is in a little pot that the kettle sits on and you feed fuel in from the top or beneath. The kids really love it because they can help stoke the fire! Of course, my MSR Pocket Rocket is more convenient, but not as fun.
