Product review (5 stars): Easy install and works great
This unit is very easy to install.  Three screws and plug in one cord (with multiple wires, but only one plug).  It took me more time to wipe out the bottom of my freezer because I emptied it to get access to the ice maker.  You do need to knock out a plastic plug in either the back or side of the water intake area depending on where your water source comes in.  On the unit I got the knock out was in a little tight and this I used a wire cutter to clip it out a little at a time to avoid damaging it.  This was no bit deal and took all of 2 minutes to do.  The whole job was about 10 minutes (not including emptying the freezer and cleaning it out).

This was a replacement and it was cheaper to buy the whole thing than it was to buy only the parts I needed.  I did not pay anywhere near the retail price though.  This full unit swap made the repair much simpler.

It is set to a certain water flow from the factory and I found it was perfect and needed no adjustment.  But if you do have atypical water pressure, it is only a screw turn to increase or decrease filling time.

I think most people can handle this repair
