FYI – Adventure Alan used some quantitative data in a stove comparison on YouTube. Not known for data, he had an air temp of 32F and a box fan on low at 5 mph. On the video he shows the test with the BRS. It only reached 100F water temp. Not enough BTUs for the weather. For the weight, under 2 oz, the reliable Snow Peak Litemax would be a more reliable, durable stove. Some hunting could turn up a used one for cheap IMHO. However, the Litemax also needs a windscreen as most stoves do.
