Review on 🔌 Wireless White Noise Sleep Sound Machine with Night Light - 7 Soothing Sounds, 8 Night Light Options - USB Rechargeable - Perfect for Baby, Kids, and Adult Relaxation by Cheryl Williams

The design of this unit is quite nice with rubber feet to prevent slipping and pictures of the controls for selecting the noise and noise you want Volume. The ring light is nice and colorful too, not too bright to distract from sleep but bright enough to provide some ambient lighting. The sounds are quiet and soothing from what I'm experiencing. When fully charged, it can work for about 4 hours, and the lightest - at minimum volume; wish he had stayed longer. It will start beeping when the battery is low, which can be distracting and wake you up. I noticed a small buzzing noise among the white noises. Its main disadvantage is that after a period of time it no longer holds cyclic noise. It either switches to a different sound or plays that static sound like it's stepped off track.
