The Primo Advantage Primo combines the concept of traditional kamado-style (round) cookers, and charcoal grills with an innovative design, premium quality ceramic materials, and a sophisticated, modern look, creating a best in class, all-in -one cooking machine. What makes a Primo better than other ceramic grills and smokers on the market today? The key is in the composition and patented oval shape. Ceramic Composition. Primo uses only the highest quality ceramic for increased efficiency and durability. Meals prepare faster while moisture and flavor remain locked inside, leaving food juicy and tender, not dry. And the outer surface stays at a safe, warm-to-the-touch temperature. Oval Shape. But it?s the versatility of our patented Primo Oval? shape that really sets us apart. Enjoy more features and options such as reversible cooking grids, rack extensions* to increase total cooking surface, or a drip pan rack* to catch meat juices. Add a firebox divider* and cook directly over the heat on one side and smoke on the other. We hope you enjoy your new Primo. Bon app?tit!
