Product review (5 stars): Fantastic!
We have been using this cook top for about 7 months now, and I absolutely love it!  We had a 25 year old electric range before this so it was like going from a junker to a porche!  The unit is incredibly responsive, I can go from a hard boil to a gentle simmer in a matter of seconds, with our old unit I would have to change burners to do this!  It is incredibly fast, just a few short minutes to boil water for pasta.  It is very easy to clean, most often I only use water but maybe once a week I use the cook top cleaner.  I have read some complaints about the noise and I can honestly say it doesn't bother me.  When simmering or cooking on a lower temperature I don't even notice the sound.  When using a larger pot/higher temperature is makes a gentle humming sound.  Most of my cookware works with this (Le Crueset, cast iron), the few pieces that I did need I picked up at Ikea which were very inexpensive and have worked wonderfully.  I highly recommend this product and would definitely purchase again!
