Product review (5 stars): They were perfect. If you are replacing this know look out ...
This was my third purchase to find a knob that will fit an older glass Kitchen Aid gas cooktop.  They were perfect. If you are replacing this knob look out for the metal insert to be stuck on the old shaft.  We could not get them to push all the was down until we realized that the old metal insert was on the shaft and keeping them from going all the was down. We removed the old metal part and they were beautiful.  Costly, but worth it.
