Summary: We had a similiar Thermador that died after 15 years (and serious use - big family etc...). This was the version of today. It came - dropped it in (after removing the old one and preparing the opening of course - very slight modification to the opening size but no problem) and connected the gas. Worked like a charm immediately. Star pattern of burners really concentrates the heat!! excellent design. My wife thinks the stainless is not as strong (thick?
Summary: "I finally got to use my cooktop to its potential this past week while cooking for a party and the holiday. It was easy and efficient. The double grates are great for sliding pots from one burner to the next or to place items from the oven to cool.
Summary: After one meal, the cooktop failed to ignite. After 3 visits from Thermador's warranty repair service, and having the entire guts of the unit replaced, it was determined that the wiring was defective which shorted the ignition module. Next time we may need NASA. It cooks great. Only time will tell if this defect, which I am told was very unusual, is fixed.
Summary: Installed granite countertop and decided to replace our old Thermador cooktop. This model has a greatly expanded burner surface and variable burners sizes. As close to a commercial cooktop as you can get. We love it.
