Review on UIKKOT Mini Humidifier - 300ml USB Cool Mist Portable Cactus Humidifier with Night Light, Whisper-Quiet Operation, Auto Shut-Off - Ideal for Bedroom, Office, Car, Travel (Pink Cactus) by Amy Wilson

The thing is small but mighty! I use it to water my plants and love that it's a cactus :) There are three settings: - ON (continuous flow) - Partial (a few seconds, a few seconds off, repeat) - Light only I use the partial setting because with continuous flow the water runs out too quickly. It's a small humidifier, so don't expect fog all day. I put it in my indoor greenhouse and it's more than half gone in 1-2 hours. But that's all I have to do, so this works great for me!
