Product review (5 stars): First one died, but the seller is A+ and got us a new one and it's absolutely A-OK!
I bought this based on the reviews I'd seen.  I'm not sure if I even needed to replace my original, but I wasn't getting ice so I got both the solenoid valve and new maker (honestly, it was probably the valve due to a catastrophic water softener failure with resin beads).

I received the ice maker, and learned quickly that it's not hard at all.  A small nut driver to remove two screws, unplug the harness, and it comes right out.  Put the new one in, and voila!  We had ice for a couple of weeks but then we hear a popping noise.  Removed the cover, and saw the nylon gears slipping against each other.  It still kinda worked, but wasn't right.

That said, I contacted the seller through Amazon messaging late on a Friday evening and got a response back later that same evening!  I wasn't expecting to hear anything until Monday.  They had another one shipped out right away.  This one purrs like our orange cat and makes a boatload more ice than the first one we got.  Super duper excellent seller.  I can't give them enough kudos.

I'm expecting this one to last longer than that first one.  :)
