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

I've had this for 2 1/2 years, bought it after having my fourth child, and I wish I had bought one for my first. It's been INVALUABLE for traveling and naps/bedtime. It takes the stress out of your kids needing to nap in places they aren't used to(like when you travel for holidays, etc) because it gives them something familiar and also provides a great noise barrier. This doesn't play a sound like a song, if that makes sense, it creates the sound mechanically so you don't have to worry about a track looping and sounding weird. You van adjust the sound by twisting the top and sides too ways, and there are also two volume settings, louder or softer. Buy it. It's AWESOME.
