Replaced the burners caps with new. I was concerned they would not fit as the website stated "approximately 3 inches, approximately 2 inches & approximately 4 1/2 inches etc.". When measuring my burner caps, they were slightly larger (by approximately 1/4 "), but I took the chance and all fit perfectly. I was amazed at how quickly they arrived too. I would definitely use Appliance Parts Pros again.
