>>1576326>>1576397If you're going to get one of these things get the biggest one they make. I bought a medium sized one for use in a park that didn't allow open fires. Could barely boil water with the thing. I think the problem is that it was tool small to have air flow around larger diameter sticks, and the small diameter twigs you're meant to feed it with just don't produce enough BTUs.
Still, a fire is nice to have for morale and entertainment, so if a Bushbox is the only way you can have a fire it's not completely pointless. Wouldn't rely on it for cooking though.
