What buyers say
From Amazon customer reviews.
Owners on their second or third Masterbuilt propane smoker say assembly is straightforward and the unit holds steady heat, with several reporting good results on chicken, pork shoulder, and ribs and one noting a prior unit lasted seven years outside uncovered. The clearest complaint comes from a buyer who could not get the temperature below 200 degrees, had smoke leaking from both door edges, and needed to constantly relight and adjust the propane valve; another reviewer separately warns the side door latches get very hot to the touch during cooking.
