Review Content Great Product unlike any other! This is easy to use, it has many different basic sounds, and additional sound overlays. Great volume and tone control. PLUS, it is NOT an alarm clock or a radio. Love this product This is the second time I bought this product. I use it every night and take it with me on every trip. Cannot sleep without it. Digital Sound Soother Relaxes me during a hectic business day. Decided after reading "Blue Mind" that anwave machine might be an interesting way to assess the prmise of that book. Easy to use Easily blocks out "noise" or a too quiet environment to sleep.
