Product review (5 stars): The best and well worth the price
The best and well worth the price.  I will never go back to gas.  I agree with all of the other positive comments.  I use coffee filters under the pots to prevent the possibility of scratching and my surface looks brand new after 2 years.  I also use a silpat under a cast iron griddle across two burners.  Another great thing that I did not see in the other reviews is that all my pots and pans including skillets still look brand new.  This cooktop revolutionizes surface cooking - I love it.
