After several years of contemplating if we were patient enough to switch from gas to charcoal we decided to purchase a BKK. After two cooks I was entirely comfortable with the keg and we were impressed with the meals that were cooked on the Keg. The insulated steel is very efficient and I cannot believe how little charcoal is consumed with each fire up. I really did not believe that the keg could be shut down after cooking and that the remaining charcoal would extinguish and be conserved. I have no regrets with this purchase and our dinner guests want one.
