Review on Portable Mini Personal Evaporative Air Cooler and Humidifier with 3 Wind Speeds - Ideal for Home, Office, Room, and Travel by Marco Maurer

It's very easy to use, you just put some ice and water on the bottom, press the button and you're done. It's small, so don't plan on using it to cool the whole room, but you can't go wrong for the price. Also, if you just want to add some moisture to a room with the bonus of a cooling fan, then great! I keep mine right next to my bed and it helps me sleep better.
