Review on Portable White Noise Sound Machine - Yogasleep GO With 11 Soothing Sounds For Sleep Therapy, Office Privacy, Meditation, Pink Noise Sleep Aid For Baby & Adult, Great Registry Gift by Derrick Wilson

I am super impressed with the amount of noise this little machine can make. It does not sound electronic in my opinion, just a soothing (brown) noise. There are several white noises to choose from but I tend to like the lower sounds.Battery life: AMAZING! I fully charged it while using it and then unplugged it. It ran for over 12+ hours with just the battery!Size: small enough to throw in my cosmetic bag for travels. I like to listen to audio books while falling asleep so using my phones noise app will not work. This is the perfect size and gives off amazing sound!
