In my short experience with my Searwood I strongly believe it is a vast improvement over the EX 4 Smoke Fire. It is better built with many minor changes including pellet hopper, smoke di fuser, auger design and glow plug. It has taken me a little time to get use to the control module but all in all I am more than pleased.  I also must comment on Weber's support and their listening to me with the problems I had with the Smoke Fire and have always made things right.
