Product review (1 stars): Don't buy this!
I did a kitchen remodel a little over a year ago. The Thermador was the most expensive cooktop, but I cook a lot and really did want the best. The sales guy claimed that this stovetop was the best in the store, and that the star shaped burners gave greater heat and efficiency. Firstly, it is VERY hard to clean around these stars, so even if it is more efficient, who cares, if you can't get into all those crevices? Also, almost immediately, and tho following the directions to the letter, this cooktop started to stain. I began seeing brown spots, especially around the burners, but now, they are spreading to the sides and surface of the cooktop. I called 'customer service,' which is a loose name for 'customer refusal.' They told me that the staining was a 'cosmetic issue.' I couldn't believe it. Who would ever buy something called "stainless steel' that gets stained? They offered to send some service guy out if I paid for it. I finally got them to agree to not charge me, so a guy came out...and basically told me that as a 'cosmetic complaint,' they could do nothing. What if our sinks, and refrigerators and stoves all got brown stains - is that cosmetic?

So, not only are those star-shaped burner a bad gimmick, I think Thermador has bought an inferior form of 'stainless steel,' and they don't want to own up to it. What consumer would want a very expensive stovetop with brown spots spreading all over it? Save yourself a lot of trouble and don't buy this stove!
