Product review (5 stars): Great cooktop
The center burner boils water so quickly.  I love being able to have several things going on the cooktop at once as well.  Loving it.

UPDATE 11/28/16:  I love the center burner, but last night I had two skillets on the center & front left plus a small sauce pan going on the front right.  I've never been able to cook so effectively because those back burners, let's face it, aren't as convenient to use.  It's wonderful.  If you only have the space for a 30" cooktop, this one is a great option.  It makes cooking fun!!!
