Product review (5 stars): Works Great.
This fit our drier perfectly, fixing the knob that had broken after years of use. This knob looks a little different than the original (which was a Kenmore model), but it fit perfectly on the "D-shaped" post from the timer assembly.

Tip: On my broken knob, I was able to find some part numbers molded into the plastic. A web search revealed the correct part number.
