Product review (5 stars): Great.
Appears to be OEM. Fast shipping, easy fit.  I replaced the plastic knobs on my GE Cafe range because the shafts all split. These are much easier to clean, and nicer to hold and turn because they are metal, and their weight makes the action smoother.  But they do get hotter when the oven has been on for a long time. Also, these knobs are a different diameter from the plastic knobs - so if you mix and match it doesn't look right. Buy a new set, and also don't worry about the space between the knob and the bezel - it seems like a big gap but you get used to it quickly.
