Product review (2 stars): Not what I expected; Unreliable reviews
The D-shaped clip that held the knob on our range top broke. I bought this to replace the knob in its entirety. Based on the product description, I expected a direct replacement, i.e., a metal knob. What I received was a plated plastic knob. It looked OK, but was vastly inferior. I pried the D-clip out of the new knob, installed it in my old knob and threw the new one away. An expensive way to replace an otherwise unavailable 2 cent part.

Let me also add that I have found that Amazon often lumps reviews and answers to shoppers' questions of similar products together so you will see the same reviews under more than one product. So, if you are looking at  "Acme Model A", you might be looking at reviews or answers for "Acme Model "A" as well as "Acme Model D" without knowing it. This can be very misleading when ordering products where such distinctions are critical. Amazon, please fix this. For now, I feel it best to buy such items from a brick-and-mortar retailer.
