It can also take tea light candles, which while it doesn't produce boiling water in say a MSR Ti cup, it comes pretty close. I tested the candle version with 1 1/2 cups water and was able to repeatedly get hot enough water for tea.
The stove comes in at just under a 1/4 of an ounce and works well with Ti mugs and hard anodized pans. If anyone wants to read up on it, the info on it is here: http://www.freezerbagcooking.com/stoves ... #147245517
