Product review (2 stars): Only 2 burners
All downdraft cook tops are, according to their manufacturers, submarginal at removing odors, heat and what you would expect a vent to vent. My mistake twice, first with an electric cook top and then with a gas downdraft.  Too late now, the cook top is mounted in a island with no provision for a vent. Big mistake. Also note the price for this cook top does not include the other two burners for the left side. Nor does it include the grill attachment.
