Product review (2 stars): Good product, GREAT service.
I purchased the AI 100S in mid 2014.  Here we are less than 24 months later and I have a broken unit for the 3rd time.  The first was DOA.  The second unit worked great for about 12 months then wouldn't make ice any more.  As the unit was now 1 month out of warranty, I repaired it myself.  The switch on the left front that signals for the ice Scoop and attached water reservoir to move forward or backward.  I replaced he switch and the unit worked well again.  Now, 6 months later the reservoir has a gaping crack in it and won't hold water to freeze it.  Additionally, it moved to the back position as if dumping water and remains there.  I am not pleased with the longevity of this product, I am giving the second star simply because the unit was on all the time, but it should last longer or cost less.

I bought one of these in May 2014 and it stopped working on day 5.  When I called and spoke to one of their reps (Christine), I was happily surprised at the level of service I received.  A replacement was sent immediately with no hassle and has been working great for nearly 2 months.  I may have had trouble with the first one, but what was most important was the service I received when I needed it.  It helps that the new ice machine is working great and able to keep up with the ice needs for a family of six.  I haven't had to buy ice since I made his purchase.  I am happy with my decision.
