Product review (1 stars): does not work for push to turn ranges
I cannot use this product for my electric range because there is no "stop" in the adapter that will allow the knob to push the control post down.  My range operates on a push and turn scheme, like most electric ranges, and there is just an open hole in the adapter.  You have to make your own closure on one end of the adapter to make it functional in any way.  I just went ahead and bought the actual replacement knobs rather than trying to embark on a DIY adventure with these.  So, they were a waste.
