I agree with everything that has been said. The knobs are expensive to replace and of no quality.  They break easily.  It is a shame for if u're reading this it means u already have purchased the Jenn Air and stuck.  I will NEVER have another Jenn-Air product in my home or anywhere else where I am making the purchase decision.
