Fully adjustable, organic noise!
I love this noise machine.  When compared to speaker-based models, the noise is much more soothing.  For me it is plenty loud, and there are adjustments on the top and sides for volume and pitch, depending on your preferences.  I like it loud and low!  It's very easy to turn on with just the flip of a switch.  It's not quite as portable as some smaller devices, but it's better than lugging around a full-size fan!  We take them everywhere we go, especially for the kids.  I highly recommend it.
