I have a lot of experience with this type of grill having owned other brand of grills like this. The only issue I have with this one is the fire will not shut down when the air vents are closed. It seems that the bottom vent is not tight enough and leeks air. Had to tighten the screw on the top vent to make it seal better. I am going to take if off the bottom vent and see if I cam make it tighter. Air control is important when cooking at low temperatures. Other than that this is a great smoker. A little tweaking and I will be good to go.
