What to know before buying

Listing details to confirm

Compatibility details are inconsistent in scope: the title names Original 4+1 and 6+1 gas BBQs, while the feature text says there may be a gap at the end of the Pro six-burner model and also recommends checking cast-iron grates and gallery photos. Confirm the selected BBQ's grate dimensions and model before buying. The listing dimensions are 33.5L x 30W x 2Th centimetres, with the thickness notation given as supplied.

Who is it for?

A good fit for

Owners of a compatible CosmoGrill Original 4+1 or 6+1 gas BBQ looking for both ridged and flat cooking surfaces.
BBQ cooks who want a cast-iron plate for searing or cooking foods that suit a flat surface.

Less suited to

Aggregate customer ratings lean positive, with many five-star ratings, but a smaller share of low-star ratings means experiences are not uniformly favourable. The ratings do not identify reasons for either view. For buyers, the main practical decision remains confirming BBQ fit, since the griddle is listed for particular barbecue series and the compatibility wording includes a caveat.
