Product review (5 stars): This a very nice machine for the money.
So far it has worked flawlessly.  It makes beautiful clear ice cubes that you want to eat.  Making them clear must completely purify the water.  There is no taste at all.  They make all beverages taste better.  You actually want to put these in your mouth.  A huge difference from the cloudy mess your refrigerator makes that have aftertastes.  You can make thin or thick cubes.  You do not need any plumbing.  The downside is it fills up very fast.  There is no refrigeration so once it is full, they slowly melt back into water, and the process just  keeps going.  Luma should also make a larger model that would hold more water, hold more ice cubes, actually refrigerate them somewhat, to at least keep them for a while.  The only downside is that it makes some noise, like a stream in the background, which is how it makes them clear.  I keep it downstairs.  I would recommend to anyone.  I will also say be forewarned, because once your family has these cubes, there is no going back.  I must now make them and put them in ziplock bags for my kids.  They no longer want the cloudy cubes the refrigerator makes!
