Product review (5 stars): Mr FREEZE PORTABLE ICE MAKER  MIM88
I bought mine two years ago from COSTCO and use it all the time.  It works fine.  It has not rusted or anything.

I love it.  It does state it needs to be on a stable surface, so If the other comment states he used it on a boat.  That
may be why it was showing "out of water"  and automaticallty shuts off. it may have been off balance and a water indicator was being moved back and forth within the machinery. mine WORKS GREAT and makes  different size ice.
and makes it fast too.
