I used to think it put out too much white smoke, and not the thin blue smoke. Then I read on here to use wood chunks cut down to 1 inch pieces, and fit well in the smoke generator. So I start with a few chips to get it started, then I add the 1 inch size pieces of wood chunks that I cut down from larger sizes, and they make the perfect amount of thin blue smoke. I too have the router control, but have only used it on full, haven't needed to use it on less power. The chunks make fresher and better smoke than the chips.
