Product review (4 stars): Is a good replacement for old Whirlpool burners.
Whirlpool website charges $45 for one.  I got two for $18.  My wife says they work great.  My only issue was the fit.  I even bought a matching set of drip pans based on reading reviews that these burners would not fit with the old drip pans.  With the new drip pans one fit almost perfectly, a little loose but once plugged in works great.  The other burner did not want to fit into the drip pan at all.  The side opposite the plug I literally had to force into the slot.  Other than that, I would buy again.
