Product review (4 stars): Be sure the old knob metal sleeve is removed from white peg prior to inserting new knob!!!
4 stars not 5 only because these are expensive....  ***IMPORTANT FOR THOSE WHO SAY IT DOESN'T FIT"... So I could not get mine to fit on peg.. even thought it was lined up.... until..... I realized that the Metal "sleeve" from the original knob that had broken off was still in place!! .. So if your "peg" is black, the metal sleeve must be pulled off... then the new part fits.... maybe it was just me....  but hope this helps someone else! :-).
