I had several problems with the seller, and ultimately had to be backed up by the Amazon A-Z guarantee to get a refund.

This review, though, is of the product itself. It was replace another of the same model that rusted out less than 5 years in conventional, light kitchen usage. The parts of the cooktop that bear the weight of full pots and pans are thin metal, so they bend under use, the finish cracks, and further cracking and corrosion quickly follow.

Beyond that, mine arrive packaged very poorly - in the manufacturers box, which was clearly not meant for shipping. One corner of the cooktop was bashed, and the whole thing was warped from handling. Not confidence inspiring when it contains parts for natural gas.
