I have had the Bronco for  about a month now, it is my first smoker. Build quality is excellent, the smoker weighs almost 140 lbs if that tells you anything about the materials. I have run it at 250 for 12 hours & still had charcoal left when I shut it down I expect it could have gone 14 without a refill. Temperature control is excellent, once I get it stabilized after lighting it I have had it run up to 5 hours without needing an adjustment but when it does the dual damper system make that extremely simple, clean & without need to put your hands anywhere you might get burned. It works very well as a grill as well, the only drawback there being the relatively small area of the coal pan limiting cooking area.
