On the plus side, it's very light (1.3oz on my scale) and pretty rugged. The base gives it some stability. However, it's not a great performer. Boil time for two cups is 7-8 minutes, using not-very-cold tap water and absolutely no wind. I tried a Snow Peak titanium pan (2.5c capacity), a 1-qt thin stainless steel pan, and a 1.3-liter titanium pan, with similar results. I've only tried this stove at home so far.
Where weight is the primary concern, and no more than 2 cups of water are needed, it's probably OK. A windscreen of some kind would definitely be required, as you can blow out the flame easily.
