Product review (5 stars): Still going strong after 3 years
I purchased this unit in April of 2012.  It is still going strong and has never given me any problems.  I was at first somewhat nonplussed to find that the refrigeration unit shuts off whenever the ice tray is full.  The ice cubes then start to melt slightly.  But, this is actually a blessing, since the refrigeration unit isn't running 24/7 (therefore, less energy consumption and wear-and-tear).  You just need to clear ice cubes from the small thermocouple probe on the right of the ice hopper and the unit will restart.  This has been one of my best-ever Amazon purchases!
