I have not used the cooktop extensively so far and the oven not at all.  I live alone so oven cooking is usually done in a counter top oven.  All the cautions listed about the care of the cooktop are so scary, it make it sound as fragile as fine crystal and it took me a bit to be get over be willing to try it. I'm sure as I become more familiar with the cooktop I will be more comfortable with its operation.  I have used gas cooking for many years and now unfortunately I have a completely electrical house and the standard coil based cooktop was 
not satisfactory.  I will continue to watch the reviews and share my reviews as time goes on gone.
