Product review (3 stars): I bought this ice maker on July 7, 2016 ...
I bought this ice maker on July 7, 2016 and it was delivered July 11 and installed that day.  It failed yesterday--that is, after less than 3 months of use.  The motor quit working and left the ice maker in mid-cycle which caused the water valve to remain open and flood the kitchen.

Amazon is representing this as a genuine Subzero part,  and I wondered wether Amazon is selling (unintentionally) a knock-off as a legitimate OEM part.  Regardless, I reported the matter to Amazon and, in typical Amazon fashion, they shipped me a new replacement the same day which now has been installed and works like it should.

I originally rated this 1 star since it failed after less than 3 months.  I increased the rating to 3 stars since the replacement works, though the first one never should have failed.

 Amazon, however, deserves 5 stars for the excellent customer service!
