I just tried out QiWiz's FireFly wood burning stove. At 2.5 ounces, it is quite impressive. It seems that most other wood burning stove manufacturers are making their stoves strong enough to drive a truck over -- at significant weight penalty. QiWiz gets the ultralight point of a wood burner -- which is to save weight because you don't have to carry fuel. His titanium stove is certainly strong enough for the careful use all ultralight equipment requires, and since it is so light and requires no carried fuel, it looks like a sure winner to me. I've been an alcohol stove user for years and find the prospect of dropping half a pound of fuel from my pack to be quite attractive. Best part -- my first attempt at a wood burn was as easy as could be, and, including "fire building" time, had my Heine pot boiling as fast or faster than my alky stove. I'm a fan!!!
