Product review (1 stars): If you don't mind waiting a long time for a decent amount of ice cubes, this is the one for you.
My major complaint is that it takes f o r e v e r to get about 8-10 ice cubes.  If you leave the cubes in the machine to accumulate more ice cubes, the first batch starts melting.  The above applies to both size settings.  Also it is much heavier than I anticipated.  We had planned to use it in our travel trailer but it's easier just to buy a bag of ice. I'm disappointed that it didn't work out. Plus it's a heavy duty three prong plug so it probably uses a lot of energy.
