I think Recteq is a very good company, but not all their products have been winners. I think this one may be a reach too far. I would tell anyone to get one of their excellent regular smoker pellet grills and then get a good used Weber gas grill - or even a Ninja Woodfire for grilling.
Speaking of Ninja, the Ninja FlexFlame seems to approach this desire to combine pellet grill smoke with higher heat in a better way than does this Recteq.
