Product review (1 stars): Break every few months!
These Whirlpool knobs break as easily as the Jenn-Air knobs the stove originally came with.  Have to keep replacing them over and over.  They usually only last a few months, to at most a year on the back burners that aren't used as much.  We will never buy a Jenn-Air again, nor will we ever buy a Whirlpool appliance if they can't even make a decent knob.  How embarrassing for these two once previously well-respected brands!
