Product review (5 stars): A great cooktop
This is a truly great cooktop both in terms of style & looks and functionality.  I have had my unit, gloss black cooktop with 4 burners and retractable vent van, for about 10 years and it continues to function perfectly.  The unit is inset into a granite countertop so the entire countertop/cooktop is flat and even making it easy for cleanup.  The touch controls work perfectly, and I especially like the timer function -- you can set a timer for any or all of the four burners as well as well as the vent fan so they will turn off from 1 to 99 minutes.  I have never found anything that has all the features and functions of this Caldera unit.
