Pros & cons

Primo Oval XL 400 All-In-One

  • ✓The oval firebox with its divider gives a genuine side-by-side hot and cool zone, which round kamados cannot replicate
  • ✓Made in Georgia — the only major ceramic kamado not imported
  • ✓151-850°F is a wider published range than Big Green Egg's 200-750 or Kamado Joe's 225-750
  • ✓All-In-One ships with the cradle, shelves, heat deflectors and divider, so nothing else is needed to start cooking
  • ✓One of the tallest domes in the category, which lets whole birds stand vertically
  • ✗Sold only through dealers; Primo publishes no price on its own site, so street price varies by region
  • ✗$2,299 puts it against a Big Joe II and above a Big Green Egg Large with change to spare
  • ✗The oval shape is off-standard, so third-party kamado accessories mostly do not fit
  • ✗250 lbs and no factory ceramic-only option below this size in the oval XL body
  • ✗Primo's own product page omits price, dimensions and warranty terms, which makes comparison shopping harder than it should be

Primo Oval LG 300 All-In-One

  • ✓The oval shape gives a genuinely usable direct and indirect zone side by side — the one structural advantage Primo has over every round kamado
  • ✓300 sq in base plus an optional 195 sq in rack system takes it to 495 sq in without a second grill
  • ✓151°F at the low end is low enough for cold-smoking cheese and fish, which most kamados cannot hold
  • ✓Made in Georgia, not imported, and the ceramic carries a lifetime warranty to the original owner
  • ✓152 lbs of ceramic holds temperature overnight on one load of lump — a 14-hour brisket is a single fill
  • ✓All-In-One package ships the cradle, shelves and tools together, so there is no $400 accessory surprise after delivery
  • ✗Primo publishes no prices at all — you are at dealer discretion, and street prices swing several hundred dollars
  • ✗primogrill.com is a brochure site; there is no direct-to-consumer purchase path and no maker-side reviews
  • ✗152 lbs in a cradle, not a wheeled cart, at this price — a cart or table is another purchase
  • ✗The oval grate means round accessories (pizza stones, most aftermarket deflectors) do not fit; you buy Primo's
  • ✗Ceramic is fragile in a way steel is not, and a dropped lid is a several-hundred-dollar mistake
  • ✗Thin dealer network compared with Big Green Egg or Kamado Joe, so warranty service depends on who is near you
