Product review (4 stars): More than met our need
I bought this item for my wife, who every day would keep filling her big Nalgene container with ice and her combination of ice tea and lemonade (and our daughters were copying her).  Even though we have a built-in ice maker in our Sub Zero, it was not keeping up, and we ended up buying bags of ice from the store to have enough.  This new ice maker has solved the problem.  It makes cubes every 6 minutes, and produces more than enough.  We have not run out since.

I have only two negative observations:  one is that if we don't use the ice right away (like overnight), it melts into the reservoir (where the water is recycled into more ice cubes), and if we want to use the residual ice it is melted into small pieces or is stuck together.  But that hasn't been a big deal, and when we are using lots of ice it doesn't have a chance to melt away.  The other is that the ice did have a plastic smell/taste for awhile.  That was lessened by running vinegar solution though it a couple of ice cycles, and it finally went away with time.  The ice is fine now.

We keep it near the sink for convenience of refilling the reservoir.  I like the portability, and plan to take it to our family reunion this summer to increase our available ice, since we go through lots of it there.
