Product review (3 stars): Tempermamental as an old mule, but it's lasted 2 years
We bought one of these ice makers over 2 years ago from Sam's Club and it's been running almost non-stop since then.  Here's some peculiarities we've discovered about this machine:

1.  Only use room temperature water.  If you use cold water, sometimes it will shut down and the "add water" light will come on, even though the tank is full.

2.  Don't use in a cold room.  Same as above, if the water in the tank gets too cold, it'll stop working.

3.  Be sure to turn the unit off before adding water.  Turning it off will dump the water in the tray into the tank; if the tank is already full this will cause it to overfill, soaking your ice cubes in water.  This will make the water cold, which causes the unit to shut down.

4.  If you're trying to make a lot of ice, either empty the ice basket frequently or move the cubes towards the front of the machine.  If they stack up too high in the rear, it will trigger the ice full sensor and the machine will shut down.

5.  Make sure you reinstall the ice basket properly; if it's crooked, it'll trip the ice full sensor.

6.  Use both handles to remove the ice basket.  While ours has lasted 2 years so far, it doesn't really feel all that particularly strong and if it breaks, the ice maker is basically useless.

7.  Use filtered or bottled water.  Anything that's in the water will end up inside the works of the ice maker, so the purer the better.

8.  Even if you use filtered water, you will still have to clean the machine periodically.  It tends to build up a nasty film on the inside of the tray.  It's REALLY hard to clean in there, too.  What I do is hit the power button, then when the tray is about half-way down, I have someone pull the plug so that the tray is stopped where I can actually get to it.  Then I empty any remaining water from the tank.  I use a paper towel wrapped around the end of a butter knife to get around the metal cooling tines and carefully clean the inside of the tray.  You'll be disgusted at what accumulates there.  I also wipe down the tank and everything else inside.  And finally, I run a small amount of white vinegar through the system a few times, followed by several changes of clean water.  Press the power button just as the tray fills completely, that'll dump the water and save you some time.

9.  Never use hot water.  Just trust me on this.  I'm lucky the thing still works.
