Product review (5 stars): so it's probably not good for parties
This product does what it is supposed to do.

Before you purchase, you need to consider what you are looking for.  This product does not produce a lot of ice, so it's probably not good for parties.  It seems to be slow starting-up; the first batch of ice takes a while.

You need to keep an eye on it.  When the ice basket becomes too full, it stops producing.  Less frequently, the water supply runs too low.

The design is ingenious.  Most, if not all, of the energy goes to producing the ice, as opposed to refrigerating the produced ice.  So the ice melts back into the water reservoir.

I would not suggest it as a supplement to a ready supply of ice.  In our house, the ice-maker in our refrigerator has malfunctioned.  This unit provides us with ice as we need it.

This is why I give it five stars.  It does exactly what it promises to do.
