Product review (2 stars): They work, but WHY would Jenn-Air put plastic knobs on a stove?
I guess my poor review should be awarded to the Jenn-Air cooktop itself because I'm aghast that such a nice cooktop would be outfitted with PLASTIC knobs.  Unbelievable.  A hot pan accidentally shifted too close to the knob will melt it, and the plastic part that attaches the one of our knobs to the stove broke a few years ago.  The replacement parts work, but I'm really irritated to have to spend money to buy a replacement.  Like Price Pfister, they should replace faulty parts for free, with no hassle.
