Product review (4 stars): Easy and Effective
I installed this about 4 months ago and it still works perfectly.  The switch is louder than the OEM part I replaced and is very audible when the burner clicks on/off when set at a mid-range temperature.

The instructions were simple and made some assumptions that you use a bit of deductive reasoning.  Simply put, if you're replacing an old unit, pay attention to how you take it off because there are multiple ways this could be installed - the wiring options vary.

The metal prong that the knob gets pushed onto can be trimmed to length and seems to be sturdy enough to last a long time, just make sure to cut it correctly (a little longer than you expect to need) so that you don't end up cutting it too short.  Remember, the knob is a 'push and turn' knob so it requires an extra 1/8-1/4" of extra room.  The knob is a little more stiff to push than the OEM, but doesn't affect functionality.

There are also extra sleeves to fit inside the knob, providing a snug and adjusted fit which nicely makes this an actual 'universal' replacement part.

4 stars for being easy to install and functioning properly, but not higher because fo lame instructions and it doesn't operate as smoothly as the OEM part I replaced.
