I found those burners too weak for stir-frying. I suspect that unless you have special ventilation, a burner that's hot enough for wok cooking will not be safe for indoor use. Ours is used outside because that's where the gas bottle has to be kept and because apparently it generates too much carbon monoxide to be safely used inside. And because we have three small children and this thing burns with a foot-high flame like a jet afterburner. It's great fun
