This is working great NOW. The main burner was not heating evenly. After reading Scarpa's review, I removed the top and found 7 of the 8 rubber spacers under the element were loose inside the cooktop. After reinstalling then correctly, the unit works as it is supposed to.

I would have given 5 stars if not for poor manufacturing. The only way the spacers would have come loose is if they were not installed correctly the factory. [This review was collected as part of a promotion.]
