Takes some getting use to, but works great after you do!
So the text below is what I had originally written...but I wanted to come back and update because once you get use to the noise and realize how much it blocks out it real is a fantastic little machine.  Water, or birds or all those other sounds don't work as well.  My daughter is now so use to this she had to download an app that makes this sound while traveling (she has a very hard time sleeping). So ignore my earlier review.  This thing is great once you get use to it.<br />______<br />I was hoping for something that was a little more quiet, this unit is very noisy, if you are trying to use it in a bedroom setting it is almost impossible to sleep with it on as even on the quiet setting it is very loud.
