Review on Adjustable Cool Mist Humidifier - Quiet Ultrasonic Humidifiers for Baby, 2.2L Vaporizers for Bedroom and Large Room - Auto Shut Off, 360° Nozzle, 24 Hours Runtime - Portable Humidifiers for Home, Office by Maurice Cunha

Humidifier Used 2 weeks, no complaints. I used to have humidifiers and they almost leave a puddle of water on the surface of my bedside table and on the floor even at low temperatures. I set these to the max for about an hour or two, then lower them to about 40% right before bed and leave them on all night. In the morning I hardly feel any moisture on nearby surfaces. I will update the shelf life information in the future.
