First, I can hold the burners while they are running, second who wants a burner to be at 1000F when it's not being used, defiantly not me. The idler valve is made to run the forge at the same pressure, but using less gas. You can tell from the video and from using it, that you are using less gas. When I am doing normal forge work, once the forge is up to heat, I simply just turn the forge off, rather than have it on idle. Forge for 30-60 seconds, and then flip err back on, heat in about 30 seconds, real efficent, but if you're doing larger work, like 5/8" and up, just turn it down to the point of where it's almost about to backfire back up the burner - where you get that turbulance in the burner and it sounds like a motorboat....that's bad - it should sound like whoosh, whoosh......whoosh......whoosh, and the flame will kind of flicker in the forge when the idler is set correctly. You should like it a lot if you ordered it.
