I like it for the office, not so much for home
I didn't know what to expect from a white noise machine.  It makes a swhooshing sound all night long and i didn't really like that.  So I brought it to our overcrowded office where we practically sit on top of each other and it was greatly liked. Somehow the swhooshing sound is calming and softens the loud voices. So I ordered a second one for the office.  The first sound conditioner was the dual speed, the second the one speed.  The one speed is all you need.  I bought a Nomad sound machine for home and like the variety of sounds. I don't use it much either now as I am adapting to the sounds of living in the city.
