Product review (5 stars): The factory replacement part with fast shipping!
I got this in two days and it is the exact same piece that broke on my dryer.  So easy it was an easy fix and looks great.  I was tempted to take off a star or two as there is no reason a knob should break with normal usage, and so this may be a bad design, but it lasted 10 years the first time so I can not be too critical.
