Product review (5 stars): This device is terrific! When you first fill it with water
This device is terrific!  When you first fill it with water, it takes about 20 minutes or so for a couple of cycles to really get a decent amount of ice.  After that, it cranks out ice every 10 minutes or less and keeps up with 4 adults enjoying various beverages all afternoon and evening.  When the ice melts, the water goes back into the reservoir and it makes more ice!  How cool is that?  It is a little on the loud side but not so annoying that you notice it all the time.  Highly recommended!
