Product review (4 stars): Works well
I purchased this to have a constant supply of ice in our common area in Afghanistan.  Since our living compound is on 220V I had to use a power transformer and found that a minimum of 1000W was needed to make ice.
The only issue I found is that when power is interrupted (a common occurrence over here) that you have to reset the power to the unit manually.  After a power outage, the power light will blick green until it is pressed again.
Other than that, it will make enough ice for 4 or 5 cups before the bin is full.  This isn't something that would make ice for a party or cooler without constantly moving the output product to another storage area.
