Product review (3 stars): Works good, likely refurbished, time will tell
It installed easily and worked well right away, making uniform ice.  I do question whether it is OEM, the one I received was in a box with the Whirlpool name all over it but I suspect this was a return or possibly a refurbished item.  the packaging was not sealed, and there were some greasy marks on it.  other reviews alluded to this so I wasn't completely surprised.  Note this will be my second replacement ice maker the 1st one was the <$50 RIM unit that has the white ice tray. It never made ice uniformly and only lasted about 3 years.  I went with this one as i believe the grey ice tray is OEM.  So will see how long it lasts
