This Works!
I have been using Nora for quite awhile now, and all I can say is that it works. My wife is much happier, and I wake more rested than before. I have a product support tale to tell, too. One day the compressor element of the unit stopped working. I send an email to them detailing the problem along with the serial number.  A few days later I had an entirely new compressor in the mail. It works fine, and I have recommended it to others, as I do  now to you.
