I also upgraded my Blaz'n to the Savannah Stoker Tom. The Roanoke controller worked as it was programmed at the factory, but I had to fiddle with the settings, with Savannah Smoker's help, to get it close to where I wanted it to be. But..when Hurricane Irma hit my controller got damaged by not only moisture, but with spider nests and a large beehive on the inside of the controller. I never thought about cleaning inside as I thought it was protected. I also never cover my grills so a lot that moisture was on me. But I am EXTREMELY happy with the Savannah Stoker. Once I learned the difference in parameter settings (again with the help of Art (Savannah Smoker) I have it dialed in to within a couple degrees of what my Smoke is reading. I should have changed it out sooner as it would have saved a lot of headaches.
