What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Primo Oval XL 400
One whitelisted tester, Reviewed, covers the Primo Oval XL 400 within its 2026 kamado roundup, but its write-up is derived from specs and user reviews rather than hands-on cooking: first-person testing language appears only for the other grills in the guide, while the Primo entry uses hedged phrasing ('is said to be', 'a couple user reviews mention'). No lab measurements exist for this model. Single-source, no cross-source corroboration. (1 sourced review.)
Praised: Oval shape enables dual-zone cooking; High lid fits whole chickens and turkeys cooked vertically; One of the biggest ceramic cookers, high capacity.
Flagged: Heavy lid is hard to lift; 'Cool touch' handle can still get hot; Sold bare-bones; cart/table purchased separately.
