I have only been using this machine for 3 days.  It makes ice quickly.  The cubes fall into the basket as one sheet of cubes.  There is no way to see how much water is left in the tank.  I have found that if I fill it once in the morning, afternoon and evening, I never run out of water.  So far, I am really liking this ice machine.  It is quiet except for when the ice hits the basket, which isn’t a big deal for me.

Revision:  The water tank temperature stays very warm, between 80-90 degrees according to the screen on the ice maker.  I’m waiting to see how long it takes for the water tank to get slimy.
