[This review was collected as part of a promotion.] I was disappointed in this purchase. First, it is very expensive for what it is, that being a single piece of cast iron. Second, when used with an authentic 14 inch round-bottomed Chinese wok, it doesn't work well. The wok is not supported and wobbles dramatically. The supports are not tall enough to engage with the wok. The cooktop it is paired with is the 30" five burner 800 series.
