My father bought four, five, six of these so-called "air conditioners" that you fill with water and attach to your computer. They don't even make a good fan, never mind an air conditioner. You'd save time and get better results by pouring the water over your head as pour it into that Polaire thing. And by the way, don't ever let the thing tip. It has four holes in the bottom and if it tips even the slightest, the water will run out onto your table/desk/whatever. Waste of time and money. User's recommendation: Don't buy.
