Just saw this posted by Overland Expo on Facebook and thought it looked interesting. Seems like a simple design that wouldn't add a lot of weight or take up a lot of space in a rig. I probably wouldn't use it as my main cooking unit, but it could certainly serve as a backup that. Anybody ever tried one before?
