Product review (4 stars): Makes my range look so much better
I was skeptical after reading some reviews, but I'm glad I bought this set.  Even though the inserts may not all be punched out on both sides, you only need one side to be punched out to fit on the gas valved stem.  I need to push down to turn the gas on and these knobs worked perfectly. I had no need for a replacement for my oven knob, but this set is inexpensive, worth buying and make my range look so much better than it did.
Shipping was quicker than indicated, too.
