Product review (4 stars): worked for one meal...sort of (Updated)
Installed it and boiled a large pot of water to check it out with no problem.  Later that day was cooking dinner and one side stopped working.  Called Bertazzoni to tell them of the problem - they contacted a repair service to come fix the unit.  The next two days [the side that still worked] did fine.  Cooked dinner tonight and the other side stopped working so will call Bertazzoni tomorrow to tell them.  Good thing I kept the old cook-top so at least I can cook until this issue is resolved.  I'll update this post with a follow-up.

Update (2/28/13) Bertazzoni said that it is so rare to have this problem they wanted to have the unit checkout by a repairman.  It took two weeks to get the repairmen to look at the unit.  He stated "yep you're right - it's dead so I'll have to take it to the shop.  He called later that day to tell me it will take Two weeks to get the parts for repair so one month now without the new cook-top.  So far I am not impressed...

Update (4/9/2013) March 14 the repair shop called to let us know that the parts were not available and Bertazzoni would replace the cook top. The new cook top was installed on March 19.  We have now used the new cook top for 3 weeks without a glitch - we love it.  Based on our experience with the working cook top I will rate it 5 stars but based on the experience with the manufacturer will only rate it 4.  Since the initial conversation with Bertazzoni in Feb. we have never heard from them - am were told then that we need to work with the seller not them - I am not impressed with their customer service.  I do understand that once in awhile you get a lemon but I would expect the manufacture to [quickly] rectify the problem and not tell me it's so rare that their products fail so it needs to be checked out and take 2 months to do so.  Hopefully this unit will work for us for many years.  If not I'll go back to Frigidaire.

Incidentally, I intended to also purchase the [Bertazzoni] double oven but due to our experience with this cook top we decided to go with the Frigidaire professional.
