Product review (2 stars): updated review - knob has broken after only 15 months
I've had to update my review - after only a little over a year, this replacement knob has broken and can't be repaired.  It hasn't gotten any sort of heavy use, as we rarely use the fan on the cooktop.  It is very flimsy, so I'm sure that contributes to how quickly it has broken.  Not sure I'd buy this brand again.
