My problem with the red box smoker was me not the red box I think I love it now I lit 1 chimney full if Kingsford briquettes in a Weber chimney waited until they were completely ashed over with the water pan full of water held temp around 250 for almost 5 hrs I raised the charcoal insert about 1 1/2 inches with 4 bolts 1 in each corner about every hour opened firebox door and shook the ashes I had clean smoke during the entire cook I was a rush to judgement on this smoker and it was me not the smoker
