Product review (4 stars): Excellent stove top, looks great, but requires careful handling with cleaning
We just purchased this cooktop to replace our much older Thermador Cooktop.  I had looked at others because we wanted a griddle and the new Thermador didn't come with a built in griddle.. Just as I was about to cave into a Bertellezoni, our salesman told us we could order a griddle that fits exactly over the central burner.. problem solved!!!!

It is a fantastic cooktop!!  Love that the blue light shows when the gas is on, because sometimes hard to see the flame in the morning light. We also got the back downdraft which looks specactular with the cooktop and luckily, with just a little carving, fit the previous space perfectly.

My ONLY complaint is that the stainless steel is hard to clean and scratches easily. Be very careful how you clean it. Do not use anything too abrasive. There is already a stain on the stainless, very faint, but I have been unable to remove it and we have only had it six weeks. But still, I am overall VERY HAPPY with this product and looking forward to using the griddle.
