Product review (5 stars): Economical and nice back up for parties
I received this unit as a review sample. First, I did make a few test batches of cubes and can confirm that it will  produce the claimed twenty-seven (give or take a few ounces) pounds of ice in a twenty-four hour period. Do note that it will not do so all at once. Each batch cycle will produce a little less than two pounds.

A cycle takes up to twenty plus minutes, depending on the ice size that you select. The smaller ice is made a little faster than the largest of the three different 'cube' sizes. Moreover, this will only store a single cycle's worth of cubes, so if you are using it at a party it will require some management of the completed cubes as well as refilling the maker. Still, it will efficiently product ice on a nearly continuous basis as long as you manually transfer the finished ice to insulated coolers as well as keep the reservoir filled between cycles. In that respect the performance is very impressive, and each load of ice is substantial.

In my title I mentioned that this is economical. It is. The entire unit draws about two hundred Watts (two old style light bulbs), so the refrigeration system inside is pretty efficient. There are some operating requirements that you need to heed. Foremost is ensuring that the side vents are not blocked. Also, it is not designed for outdoors use, so factor that in if you are purchasing this for a pool party or BBQ.

The manual cited that high ambient temperature can also hamper operation, so I am extrapolating that this unit cannot be placed in direct sunlight or in overly hot spaces. I have  not tested those environments, but do need to warn about potential limitations. I do not view this as a design flaw since many appliances have the same restrictions, but, again, want to set expectations.

This unit can can easily keep a party of twenty supplied in ice for drinks. Plus, when you factor in the low energy consumption that I cited above this makes an excellent personal ice maker.
