I’d caution against buying any of them for pans that large, honestly. Manufacturers are not required to match the size of the coil to the ring that indicates the ‘cooking surface’ on the cooktop. I bought the Duxtop one that all the review sites seem to recommend, and while it’s still a capable burner, the actual coil does not extend to the full diameter of cooking surface (it’s a lot closer to the minimum pan diameter, about 4 inches). No pan is actually going to adequately compensate for this, I’ve tested it across several different cookware materials, and multiple different brands of multi-ply stainless steel. You end up needing to treat pans somewhat like a wok, with hot/cold zones and a very clear temperature falloff when not in the center of the pan. I didn’t have issues with warping, but I was also extremely careful when it came to preheating pans that were 10 inches or more.
If you do decide to purchase one, you need to find the size of the actual coil itself. Most manufacturers don’t readily provide this information, taking advantage of the fact that most consumers are unfamiliar with the technology or won’t nitpick about the uneven heating. I hate it, because it can lead to an experience so bad that it turns people off from induction.
