I've had my
MasterBuilt Pro (Propane) from Home Depot for about 10 months now and really like it.
Haven't tried to burn only charcoal because I don't like to spend that much time tinkering with temps when cooking. I like to do other things at the same time, not be tied to the smoker.
But I've seen temps fluctuate around a lot I think because of the thin metal sides. So what I've done is put a 10" square patio brick on the lower rung and it really has helped stabilize the temps!
I love the fact it has a couple wheels to move it around and out from under the patio, plus if the wind is blowing I can move it to accommodate that.
It does flare up the wood in the burner at times, and the way around that has been just getting the flames away, or use the A-Maze-N pellet smoker.
My 3 gripes:
1) Thermometer on door is apparently just decoration, I have a Maqverick ET-732 thermo and love it now.
2) The cooking area is only 12"x12", so unless you cut your ribs in half, diagonal they will sit taking up one of the four shelves.
3) I happily use an A-Maze-N pellet smoker, but I think there just isn't enough oxygen to keep it consistently lit properly when its inside the smoker.
I made a little offset for the A-Maze-N that jams into the side vent, and it seems to work wonderfully. (no patent pending, haha)
