My wife is very happy with the look of the chrome replacement knobs -  the originals, after seven years of heavy use, had become gummed up and disfigured due to heat escaping from the oven. Easy enough to install, although neither of the included adaptors provided a tight fit. That problem was satisfactorily solved by using a little latex caulking in the adapter hole. The only disappointment is that new knobs are slightly smaller than original, but this is a generic product and I am happy not to pay for a manufacturer's replacement which I am sure one knob would be priced the same as this kit. And those same knobs would soon deteriorate. It will interest to see how these knobs hold up.
