I've wondered the same thing many times. I'm surprised other companies haven't copied BK's air control since that is what I believe sets them far apart. Could it be a patent? They have been using some form of that air control system for nearly 40 years. Don't patents expire in 20 years? So why don't we see more of that design on other stoves? It's a good question...maybe someone with knowledge will step in and explain.
Yes, that's exactly what I've been pondering! Most/all of the rave reviews about BK stoves are specifically about the incredibly long burn times. I don't think people buy them for the looks or price. Now your stove may have another thing going for it because of its massive firebox size. I know cat stoves can have longer burn times vs secondary stoves so is BK using cats developed by NASA? The cats are probably manufactured by and shipped in from China so why isn't the other companies scrambling over each other to replicate BK!? I know some say stuff like BK is great at long, low burns but that's not what everyone is after. Umm, why the hell not!? A stove that is capable of doing a long low heat burn and has the ability to produce a lot of heat fast sounds like the ideal heater to me.
