I have an Auber.
I have one of the cheapest, simple vertical smokers there is.
It makes it work like a champ.
I can smoke sausages at 160f or chicken at 275f
The reason I use it is I have it on my smoker at my cabin, for example I put a venison roast on and went snowmobiling, came back to the cabin 4 hours later to a perfectly cooked meal.
its a great product.
