Review on Yogasleep Dohm Classic Gray White Noise Machine: Natural Fan Sounds, Noise Cancelling For Office, Travel, Meditation, Adults & Babies, Sleep Therapy. by Ron Chang

Have used these for many yrs and love them. Other reviews complain the noise isn't the same or loud enough. They were fine when I was in practice at my office, some yrs now, and still we buy these same ones for our bedroom and traveling. The low level admittedly does not much at all but the higher one is all we need. We do have 2 dogs in the room with us and they never quite settle until I turn the sound machine on. So 5 human stars and 5 dog stars. The others I've looked at have too many features we just don't need. This is simple and does the job of blocking out things that sound sensitive folks sleep better not hearing.
