Okay I got one, haven't tested it yet. I thought with the hefty original price tag, the "turn the burner cup" thing would have some fancy jet changing feature, but it turned out to be just open/close a few air inlets on the side to switch between gas/liquid. Gotta say that's a disappointment. One thing I do like is the hose is mounted on a swivel, not fixed like on most other stoves, makes it easier to pack and place.
