Product review (2 stars): Like the ice, just hope it doesn't break.  No Repair Support
I have the AI-210 Stainless Steel model.  It worked fine for a few months then shut down and gave no flow water or water sensor bad light on front panel.  I checked the water level and check for an obstruction blocking the inlet.  I found nothing.

I emailed Air N Water and asked about authorized repair/service shops.  I also asked about parts as I do have extensive experience in the electro-mechanical field from an early career as an instrument tech with the Air Force.  They answered my email by saying there was no repair centers.  They also didn't have any part numbers and you couldn't order them, but if they had one laying around I could buy it.

I tore this unit apart trying to figure it out and decided to change the pump.  I actually researched the internet for a half-day and found a near exact pump used in the thing--sheer luck.  Guess what, it's an aquarium pump.  So I ordered it.  It took forever to get the tubing connected--lot's of spilled water.

I re-read the manual.  I went to their FaceBook account and looked for hint there.  Finally, I gave up and just order another one (different brand with service support of course).

In process of putting the thing back together, I stuck a straw in the tubing from the pump to the resevoir.  Oops, obstruction???  I pushed harder and out popped a thimble-sized plastic mesh filter.  Guess what--it was clogged.  The manual neither shows this thing nor describes it.  I could have pulled it out in about 3 minutes and been back in business.

So--no support.  I can't recommend this thing at all, but after dinking around for over a week, I just heard ice cubes drop in the binn.
