Product review (4 stars): This is the second unit we tried. The first ...
This is the second unit we tried.  The first one would not work at all - and kept giving us a "low water" alert.  This second unit worked for one night and now the same thing.  Low water alert even though it is filled to the fill line and no ice.  This one is going back also.  So much for "made in china".
Revised reiew..........
Okay - - here is the deal.  While you can use distilled water in other appliances you cannot use it in an ice maker.  The instructions should be  really clear about this.  We cannot use our tap water, but bottled water works fine - due to the sensor.  Now that the water issue is solved, it is working beautifully
