Product review (5 stars): I really wondered if this would work... and it did!
I have a friend who has a cabin in the mountains where we have occasional parties with quite a number of friends - perhaps as much as 30 people or more over the course of a day.  We never had enough ice without having to buy bags of it and drag it up to the cabin.  I was a bit skeptical that this thing would actually work, but darned if it didn't!

I was amazed.  Once it gets going, it cranks out ice surprisingly fast.  We would start it an hour or so before people started coming in and allowed it to build up some ice and then it kept up with demand.  Interestingly, the ice is made and dropped into a tray inside the unit where it can melt.  That water is recycled and refrozen.  All you need to do is add water and it keeps making ice.  It holds a fair amount of water and I would guess I filled it a couple of times after the initial fill and that lasted most of the day.  It also shuts off automatically when full and restarts when the level drops down.  It's fascinating to watch, too.

It has some mechanicals to it so I wondered if it would last.  We will be on our third summer in 2014 and it has held up just fine.

It makes a nice gift for those folks who have parties and need ice.  It's portable, too, and can be placed where the drinks are being made.
