Been using one for about 5 years, way more convient than a woodfire when youre ready to go to bed just turn the valve closed no worries about embers blowing around, in the morning the wife loves to drink her coffee by it and warm up, then turn it off, let it cool down for a few minutes and pack it away. Also you don't smell like smoke after using it is another side benefit. The first time I saw one was on the White Rim where ground campfires are not allowed and was sold on the idea ever since
