Product review (1 stars): Not this model
I purchased a similar model to this one in April 2005 (no star burners).  The two extra-low burners went out on me in December 2007.  The appliance repair man said it was the computer control mechanism that went bad...$215 to fix (20% of the purchase price).  We used one of those burners just about everyday, but the other was used on average of about a dozen times per year.  I believe something like this should last longer than 2.5 years.  Unless they have rehauled the computer control, I would strongly suggest purchasing another brand.  When I contacted their customer service to try to get some help (a manual copy) they told me i could buy one (huh? they have a bunch of downloads on their site!!!) and, sorry they couldn't help me with the repair.  Terrible customer service and I told them so.  For as much as I paid for this and the reputation of Thermador, I expected much more.  I will never purchase another Thermador product for as long as I live.  You have been warned.
