I am loving this new cooktop. The grates are heavy and solidly fit on the rubber pads without moving one bit. The grates match up well for a seamless slide of a pot from one burner to another. Canned some homemade jam last week using three of the burners simultaneously. Used the left-hand burners with my own griddle for breakfast this morning, with excellent results. Like the lights under the knobs to let you know for certain when it's turned on/gas is flowing. One note of caution: the grates are cast iron and hold the heat VERY WELL for a while after the burners have been off.
