Great sound!
My husband and I have always slept with a white noise machine.  We got this one to replace our old bulky machine, which we've had for over 20 years.  My how they have changed!  I love the compact size of this one and the fact that it plugs in via USB.  I have a power plug with multiple USB ports right next to my bed, so this is way more convenient than plugging into a wall outlet.  The volume level is great and unexpected for the size.  There are so many sounds and modes to choose from.  (We prefer fan noise or rain.) The instructions are very easy to understand and the touch nightlight is a nice feature.  Highly recommend!
