Only downfall from when I looked at them is the drain for the water pan comes out the back. I move my smokers around often and when I do they are laying on their back. The air intake vents stick out as well. would have preferred a flush design.
Other than that I'm sure they cook just as well as any other insulated reverse flow cabinet smoker.
If you guys are interested, better jump on one soon. He is already talking about raising his prices.
