My product is slightly different than the one pictured above. My gas regulator does not have a gauge, but the new one simplifies the use of adjusting the gas. My regulator just has a knob that will open and close and more you open it, the bigger the flame and hotter it gets. It was easy to adjust the gas and the air intake to the desired temperature. I had it running continuously for over an hour and melted 5 crucibles full of aluminum. The stainless steel did not discolor like the previous painted black versions. The hinge heated up and distorted slightly, while wearing my heavy gloves I was able to adjust the lid to align and close fully. I'm very pleased with this product and would definitely buy it again.
