I got an Arctic Air for my birthday recently, and I was surprised at how well it worked. It runs at full blast for about 4 hours, and the documentation claims 8 hours for the lowest setting, which is entirely believable. The unit I got measures 6 ¾ x 6 ¾ x 7 inches and weighs about 3 lbs when full. The reservoir holds about a pint and a half of water, and the tank level is easily seen thanks to the backlit LED's. While it does some pretty silly stuff like color cycling, I prefer the blue color for night time usage.
Prices vary widely (from $12.95 to $89.00!), so since all offers appear to be the same unit, I would buy one from OnTrendsPower as they are only $12.95 there. That's the upside; there's only three cons with this little unit.
First, it is TINY; so don't expect it to cool down even a smallish room. Secondly, it's powered by either USB Micro, or has an included wall wart to plug into. USB can supply up to 2.1A ar 5VDC on a standard USB 2.0 plug, so that's only 10 ½ watts total power. So don't expect it to be anything other than what it claims to be: a PERSONAL cooling unit. Thirdly, it has replaceable filters, which is a good thing, but those cost like $10, so it's almost cheaper to buy an extra unit for that $12.95 price tag!
While the warranty (if any) isn't even mentioned in the docs, they do offer a 30-day no questions asked return policy. All in all, for the money, it's both quieter and more effective than a fan at keeping you cool. I even tried different temperatures and humidity levels and found that it works best in a low humidity atmosphere situation. As with all things like this, "your mileage may vary!"
Bottom Line: Yes, I would recommend this to a friend
