Product review (3 stars): the exact OEM... which is flimsy
This is the exact OEM part, which is great since it matches my stove.  And also sadly it is like the original, the connection to the stove is made of flimsy white plastic.  All of my original knobs are cracked at the white plastic.  I've been using my fingers instead of the knobs for the longest time but my husband finally said he wanted knobs for father's day.  What can I say?  Last time I looked the knobs were close to $100 each!  So I was so glad to see the price has gone down.  But $150 for knobs... it hurt too much to pull the trigger.  After reading about a reviewer's husband putting a copper sleeve on the white plastic... I went a hunting and finally found a similar solution.  A 3/8" lock washer!  Yes, I brought a knob to Home Depot and found a 22 cent lock washer to fit around the white plastic.  I put it on and it works great... there is no play in the knob when it is turned.  That fixed three of my cracked knobs.  The fourth knob required a lock washer and a 3/8" washer.  I guess the crack had run down too deep into the knob.  When I tried putting on just the lock washer, I could feel a lot of play in it.  Slipping on the regular washer first and then a lock washer on the tip eliminated the play.

The last knob could not be salvaged since it had a chunk of the plastic gone.  So I did buy a knob but am planning on taking it to Home Depot to find a lock washer for it... the 3/8" one I had for it does not fit.  Which makes sense because it is not cracked yet.  I hope reinforcing it will prevent it from ever cracking.  So, instead of spending $150 to have five functioning knobs... I spent less than $33!  I hope this helps you, as many of the reviews on Amazon has helped me over the years!  God Bless!!!!
