Product review (4 stars): It looks like, works like
It's a knob. It looks like, works like, maybe is the real thing, and a hell of a lot cheaper than ordering the part from GE. This is a part where metal should have been used instead of plastic. Heat from the oven, maybe from the cleaning cycle in particular, caused the plastic innards to warp and crack. I expect this to fail eventually, but I will just order another third-party knob for not too high a price.
