I really love this cooktop.  Have only 2 complaints.  It is very hard to clean up after grease splatter.  I bought the cleanser suggested by Cafe but even that laughs at grease.  I now lightly wash with water and dishwasher liquid and then shine it up with the cleanser.  Also the pots and pans easily spin on the glass.  Suggestion:  perhaps putting low ridges on the glass on the rings where the pots and pans are set would help.  Just a thought.
