Product review (1 stars): Avoid Avoid Avoid
I bought one of these.  After it had to be repaired 4 times in the first 3 months I insisted on a new one, figuring it was just a lemon.  It wasn't.  The new one was almost as bad.  Complete junk.  That's way Consumer Reports rates Thermador the MOST repair-prone brand of oven.  Check it out yourself (latest issue).  Spare yourself.
