Review on Tikaton Travel Humidifier: Portable Mini with Collapsible Water Tank, Upgraded USB-Powered Cool Mist for Car, Office, Bedroom (Blue) by Erin Bowers

Loved the portability of this little humidifier. Small enough to pack for an upcoming trip (hotel rooms can get so dry). It emits a stream of humid air well, but the device tips over very easily and when put back it takes some time, around 10-20 minutes, to get it working again. I've found putting it in a small plastic container to stabilize it well enough to fix it helps. I would recommend this item for the purpose I have described. It won't work well enough to humidify an entire room, but placing it right next to your bed at night will help a little.
