Received the smoker as a christmas gift from my family so I have been using it for 7 months. Asked for this particular smoker due to the large size. 
So far I have smoked several briskets, burnt ends, several pork roasts, smoked BBQ beans roasted corn, Smoked potatos, BBQ chicken, sausages and hot dogs. All turned out great. 
Took a while to learn to control the heat but now I am able to keep it within a 15 degree range for 8 or more hrs. Everything works great but the thermometer  is off so you should invest in a more accurate. I went with a wireless and that works great. I would buy this unit again.  The largest session was a 20lb brisket, 6 ears of roasted corn, 4 potatos (big potatos) and two pans of BBQ beans. I still had 3 shelves I could use for additional cooking
