Product review (2 stars): Be Careful----Warning
This review regards the ceramic surface only.  Utterly disappointing.  As a preface, I had a Bosch ceramic cooktop for 11 years.  Not one scratch.  I installed the GE and cooked my first meal using two brand new All-Clad stainless steel pots.  The surface was cleaned and the pots were washed and checked for any burrs.  The result after one use?  Two scratches, one I can feel with my fingernail, on the two burners that were used. The GE is shipped with a sample of "Cerama Bryte."  The GE manual states Cerama Bryte can be used to remove scratches.  DO NOT USE THIS PRODUCT.  The scratches were not removed.  All Cerama Bryte did was remove the lustre from the ceramic top leaving a haze over both scratches.  Now I have two scratches and two hazy spots on a cooktop used once.  Bosch, 11 years no scratches.  GE, 20 minutes-two hazy scratches.  Would I recommend the GE?  Only if you are not going to use it for cooking.
