Product review (3 stars): Way overpriced
Extremely overpriced for a plastic knob.  But, what can you do?  GE has you stuck.  Being on the top of the stove, these knobs are extremely vulnerable to a pan touching them, then they melt and look bad.  The plastic "grippers" underneath that hold it onto the stove are weak and break easily, which is what happened to us.  So, you can live with ugly melted knob, but when the grippers break you don't have an option.
