Product review (4 stars): you pretty much have to replace it after a few years ...
If you have purchased a fridge with this icemaker, you pretty much have to replace it after a few years because of the corrosion of the parts (sorry to be gross but you should check your ice for little specs).  the replacement part works fine.  Can't give it five stars because the design builds in corrosion as the non-stick surface in the ice tray crumbles away over years.
