Product review (5 stars): Easy and well-documented
I did have one small problem: one of the harness plugs for the water valve was bent on delivery.  I had to bend it back into place, and it is functioning properly.

This product works as expected, and installation was pretty easy.  My favorite part was the clarity and detail of the installation guide.  Some installation guides are written in broken English, with poor detail or illustrations.  This guide combined proper grammar with good illustrations, and all of the information was exactly correct.

My situation was a bit more complex because I needed to run the water supply line from a bathroom on the adjacent wall.  Despite that, I was up and running relatively quickly.

One important thing to have is patience.  Don't over-tighten anything! Check all fittings for leaks after the supply is turned back on.  After installation, there will be air in all the supply lines, so it can take a really long time (at least several hours, perhaps a day) for ice to start forming, and once it does you want to throw away the first few trays.  Also, you should use an inline water filter for best ice quality.

Good product, highly recommended!
