I was a little nervous to vet this cooktop.  I have had multiple glass cooktops that always look horrible.  I have a short attention span and 5 little kids.  I consult boil the contents over and can't get the top clean.  With the instant heart and instant temperature changes my life is so much easier!  I love that I can use the silicon mats under my cookware. I like to cook with cast iron, the mat keeps the top clean and prevents scratching. I will never go back,  this cooktop is amazing!
