Product review (4 stars): Worked fine - only a small assembly problem
The large assortment of shaft inserts was sufficient to assure something woul fit my 30 year old electric range  (Magic Chef),
and the choice of two different circular ring inserts for the range temperatures also assured one type would work on my old range.
Delivery was prompt and the product was inexpensive. It did not get 5 stars because of a bit of trouble installing due to small amounts of plastic flash that had to be gouged out of a couple inerts before the knob would mount on the stove.
