Product review (1 stars): If you like knobs that soften and deform when used on a kitchen range, then these are definitely for you.
First things first:  Knobs that are for use on a kitchen range shouldn't use a plastic that will soften and deform when exposed to the temperatures they'll encounter on the front of a range, such as when the oven door is open while you baste a turkey.  These aren't made of high-temp plastic, so they do just that.
Secondly, the metallic rings that have the settings printed on them don't stick down on the knob worth a darn.  The adhesive isn't up to it, and the shape of the ring doesn't match the shape of the knob very well, so they want to pop off almost immediately.
Thirdly, the inserts need to be glued into the knobs, or they won't stay, and I had to do some filing inside the shaft hole to even get them to fit an ordinary Kenmore's controls.

Bottom line is, I wasted my money, and my time, and ended up going out and buying the more expensive, 'original equipment' type knobs I should have paid for in the first place.
