This is a compact billy, which I principally use for making a cuppa on the side of the road, or for cooking toast for breakfast. It all packs away inside itself, and the design of the bottom of the "billy" means that almost all of the heat from the flame is directed into the heating pot, making it very fast indeed. The gas bottles last for ages. There are a range of other accessories and pots that lock onto the burner as well but I won't bother with getting any of them. There are smaller stoves around, but this is a complete unit and is quite compact. They say that the green fitting on the bottom can be used as a cup, but as a cup it's useless.
