This cooktop is a replacement in our granite countertop.  It works great and matches the rest of our appliances in the kitchen.  We particularly like that it gets HOT very fast, particularly the two larger burners.  The front large burner is actually two burners with a smaller one inside the larger one, giving us the flexibility of five burners to choose from.  Finally, it fit within a tight space in our counter that other designs would NOT work to clear our oven below.  Great design by Frigidaire! [This review was collected as part of a promotion.]
