Product review (5 stars): Quality product
Replaced another cooktop which worked fine but with updating kitchen counters wanted a new stovetop.  Decided on Whirlpool because wanted five burners and location of control knobs on right side, not in front as many have.  Unit is very attractive and works flawlessly.  The "simmer" option is quite unique and the "warmer" burner will be quite handy in the future.  I would highly recommend this unit to others shopping for a black, 30-inch cooktop.
