WE purchased this machine and plugged it in and it is working great. WE were concerned about water quality, so we installed a reverse osmosis system with it.. The ice cubes are crystal clear.
WE did miss the on/off button down on the side of the machine to power it up, but once we found it, we were good.
The only reason for the 4 is it has been running for 2 days, but we expect great things.
