Product review (2 stars): this is a FINE knob.
Buyer BEWARE! There is the older PLASTIC based knob (Sears Kenmore 80, etc.) that is identical in all respects except the PLASTIC (easily broken) threaded connection area AND NOTE: The thread size on the older plastic models and the (newer) metal models IS DIFFERENT.  This knob CANNOT replace the older plastic model(s).  Other than that, this is a FINE knob.
