I received the humidifier just in time for the winter months.  My wife and I have used it now for a few weeks.  For the most part, it has done its job very well.  The night mode is quiet and functional, probably our favorite feature.  At times, my wife has had troubles getting it to cooperate when an error message appears.  The machine says it needs water, but it’s full.  That’s aggravating.  But still, the overall function and use is great.
