Product review (3 stars): Is....this real life?
This thing works....I think?  actually, I don't know if its working, but my water tastes slightly better....or maybe thats just because its cold.  Actually this thing could be doing nothing but making the water move out slower through the spout, and I wouldnt know the difference.  But it makes my wife feel better, and it fits my fridge.  So I guess it has that going for it.
