Product review (2 stars): Sensors stop working
Note: this is a review on the discontinued AI130S purchased from Amazon from NewAir, who's exclusive distributor is Air-n-water.  Since I cannot place a review of that unit, I thought this might be helpful for purchasers of other NewAir units.

In general, the NewAir icemakers do the job and crank out ice.  The basic mechanics, compressors, etc. are fairly sound.  However... 1) the magnet used in the sensor for 'full ice' fell out, and we had to figure out how to reinstall it correctly and glue it in place.  2) It worked for the first year, but now although the resivour in back is 'full', it does not put sufficient water into the lower/front chamber.  So, it gurgles and rah-rah-rah's as it pumps some water and some air, causing terrible ice and noise.  Pouring a cup or two of water into the font solves the problem.  The 1 year warranty just does not cut it.  The manufacturer refuses to give me any troubleshooting advise other than "we'll send you a RMA form, and if you submit it we MAY allow you to return it to us to be repaired on a time-and-materials basis".

My recommendation:  I'm sure the AI100K uses similar sensors and construction...Buy an extended warranty from Squaretrade, you may need it.  Or just budget for a new one every few years.
