Review on Humidifier Essential Humidifiers Ultrasound Shut Off（Black） by Carrie Green

Easy to fill and use. It took me a while to figure out how to turn the light on (by holding the button down). Gets clogged with essential oils almost immediately so not sure why that's advertised. But it works great for a tiny bedside humidifier (with no added scent), just what my doctor recommended. Lasts about 6 hours on a lower setting, which is good for one night (does the intended job). I wish I didn't have to refill it every day but I guess it won't go moldy this way. Would buy again!
