Royal, I used the Bushcooker LT II this weekend instead of the BushBuddy. I wasn't impressed with the Bushcooker, as it needs very small wood pieces and while I can go goofing off to collect more wood, I find the BBU or Ti-Tri Inferno much more eficient because I can use bigger pieces of wood, and they are both a lot easier to feed.
Anyhow. Melting snow and getting it to a boil took me, for 1l of water, approximately 20 minutes. Its a time consuming process, but once water is slightly hot putting in more snow was getting easier, as it pretty much dissolved instantly.
