Product review (5 stars): Beautiful cooktop, but one of the cast iron grates was broken.
Just installed this today. Very easy installation. Looks and works fantastic. My only complaint, the middle cast iron grate was broken. See photo. I am waiting to hear about how to get a replacement

One of the grates arrived broken. Seller responded promptly and within 5 days had a replacement. Outstanding customer service. Would order from them again without hesitation. Well done!!
