Downside of this invention, lots of promotion but no source where to obtain it. You can find tons of information and promos about those cookers. But even contacting those given sources will let you end up with nothing, they cannot even respond to your queries. What a waste of time. Invention without use, total BS.
Poor design. It should at least be able to sustain 10 minutes of sustained output without the constant wiggling..flame outside the combustion chamber is dangerous. Needs lot of improvement.. ive designed one 40 yrs ago with blue flame and no fan
