Yes, it works very well. I LOVE it.
The only thing is with the new SnP and the stupid "daisy" damper opening that Brinkmann made, it is a little tricky getting the Afterburner to line up with one of the openings. I ended up making a new door but I could have gotten by with the stock door. I also found that if I put the juice can with wood in the grate cutout I cant keep the chunks from catching fire so I stand the can up in the corner of the firebox on the grate and that works very well.
I don't have any experience with natural gas version but I know you can get a dual fuel version if you want.
One nice thing about the Afterburner is you can take it out very quickly so if you wanted to do a charcoal smoke once in awhile, it would be easy to switch back. I don't know that I would though . . . the gas is awfully convenient.
I am very happy with mine and you would be hard pressed to find better customer service from any other company. Ed is great to work with.
Hope this helps.
