I would like to say I was very surprised at the quality of this cooker with the warming contanor. All welds look great way thicker then i expected heavy duty should last a life time if I can keep from burning it. I have 40 trees tapped and get about 20 gallons of sap a day. Im cooking with gas and it is keeping up quite well. I did put this on a 3 burner cook top that i also purchased on Amazon. Well worth the money! If your on the fence just buy it you will also be surprised.
