Cast iron grill for induction hob?

[FaintlyMacabre]

I’d like to get a rectangular cast iron grill pan for our induction hob to go across 2 burners- preferably the sort that are double-sided with a smooth and ridged side.
However the reviews are very conflicting about how good these are on induction hobs- apparently they don’t always connect well with the hob.
Has anyone got one that they would recommend (or not!). Thanks!

I don't have one that goes across two but our Le crueset square griddle pan works great on the large one on our induction hob.

Thanks, ‘normal’ cast iron pans do work well so if I can’t find a double one that’s compatible with induction I might go for another of those.
