I asked for (and got) an Afterburner for my ECB Gourmet recently, and installed it last Friday night. Did a test run on Sat and it worked great, then smoked a butt on it on Sunday. Really like the conversion, not sure if I will use it on the smaller/ quicker things as I enjoy tending a fire for a while, and will continue to use my kettle for those things. The butt turned out great (sorry no photos- my camera was at work) started a 9 lb er at 0700 and ran it at 250-260. At 1215 I was reading 190+./
I pulled it off and put it in a covered foil pan in the oven to rest a while, pulled it and ate sammies for dinner with a little slaw.
Happy and think the afterburner is a good product-
