The original cheap plastic knobs finally all broke. Ordered new one for my GE Profile range. Appliance Parts Pros had my range model number in their system so I ordered all six knobs. They are all metal, much heavier and sturdy but pricey at about $50 per handle but were a little less expensive than the same exact knobs at the GE website. Handles came within a week and were easy to install … just push them on. I dealt with Appliance Parts Pros before on repair parts for a washer and that was a good experience also.
