Product review (3 stars): It works
I was hoping for a larger variance in size between the large, medium, and small cubes. The ice maker functions by freezing a layer of ice around frigid stainless-steel fingers. As far as the cubes go- the small ones are thinner-walled, about 1/8th inch or slightly thicker. The medium is almost indistinguishable from the small, and the large cubes have a total width of about an inch, making the total dimension of the large cube 1x1.

It definitely turns out the ice, nine cubes at a time, hahaha. Each batch of nine cubes takes about 10 minutes. So after an hour, the little hopper will be full of ice, about 4c as far as dry measure goes.
