When my wife was pregnant with my kids, she craved ice that she could crunch.  We would search gas stations, to this day, so she crunch ice.  I got her this for Christmas.  So far, so good.  Since Christmas, we have eaten nugget ice everyday.  Like any refrigeration unit, it will hum a little, but the subsides when the ice is done.  The aspect that we can control it over our wife through the app also allows for the convenience of only having it on when needed or when we are on our way home.  Simple design, easy filling, and easy wifi setup.
