I have sold burner, and grill/smoker built from this smoker to American, Canada, and Australia.
A BBQ trader in Australia BOUGHT my smoker. I am sure that DR-KY knows whom he is.
I NEVER receive negative feedback from ANY buyer.
Mr.Uk made his own burner according to my sketch.
There may be some misunderstanding.
I am not sure whether Mr.UK understand me fully or not. I doubt.
