Product review (4 stars): dropped right in
This kit contained everything I needed (except a water line) to add and icemaker to my fridge that came without one.  The fridge was already set up for one, and adding the parts in the kit only took about 15 mins.  If yours was not designed with an icemaker option (with mounting points, water inlet, and electrical plug) already in the freezer, this kit will not work for you.  Sourcing all of the parts separately would have cost at least twice as much.  It actually has everything you need for about a dozen different GE fridges, and the hardest part is figuring out which instructions to follow.  The only instructions say to "use the letter that corresponds to the letter on the back of the fridge," but of course there are like 20 different letters on the back of the fridge.

The icemaker works well so far and is quiet.  It looks like the factory unit and the only issue I have is that the power cord extension inside the freezer is way too long, currently I have it stuffed down into the ice bin but that prevents the bin from sliding out to dump the ice.
