I’ve got one, just a 120V, home-use thing, but it gets far hotter, faster than on my stove. Tends to have a cool spot in the very center, maybe 3" diameter, unless you circulate the wok, and you can’t flame food by tossing it in the fire (which you can’t really do on a residential stove, either). It’s a decent approximation of a wok jet for home cooks.
