Can't sleep without it- I buy it for friends as a gift and they love it too
This is a simple machine- not much to adjust except for a more open sound and a more closed sound.  Since it is not a tape, there is no repeat of sounds- it is one sound- just white noise.<br /><br />I got it for the first time 3 years ago while living in a tiny Chicago loft with my Husband and two dogs (who loved to &#34;dance&#34; on the hardwood).  There was only a partial wall that separated the kitchen and the bedroom.  This thing was a life saver- it never killed all the noise in the loft, but it made it tolerable.<br /><br />Other uses- helps you study, covers car noise on busy streets, use anywhere you need privacy (bathroom, office, when kids sleep).
