BEST NOISE MACHINE EVER!
I have been sleeping with fan white noise for years.  This is the BEST Noise Machine ever!  I have purchased many travel fans but none are loud enough.  Then I found one that is good, but it is $50 and 3 times as big as this noise machine.  I have used it on the white noise settings for the past 3 nights, and now I can get rid of the huge box fan in my bedroom.  It should also work for my Special Needs Granddaughter who has a sleep disorder.  The music setting also has many sounds, including rain, heartbeat, birds singing and soft relaxing music.
