With this model, when you remove one of the 4 ring grates, there's a well and about a 2" space down to the burners; a wok nestles down so you don't need a ring for it.
Both the burners and oven work better than any stove we've ever used.
It's easy to clean, and a relief not to have to mess with touchscreen controls. Made in America. A wonderful tool.
If you're a Bay Area person: I got it at CG Appliance Express in Daly City, CA (adjacent to San Francisco), the best place I've ever seen for appliances of all kinds.
