## At a glance

- Reversible design offers a ridged surface for searing and a flat surface for foods such as eggs and pancakes.
- The listing says it is made for the CosmoGrill Original 4+1 and 6+1 gas BBQ series.

## Pros

## Before you buy

- 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.

## 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

- Buyers who need a dishwasher-safe plate or want to wash cookware with water as their standard cleaning method.
- Owners of other BBQ models who have not checked the grate dimensions and fit.

## Customer feedback

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.
