Pretty good, it does what you expect (if you don't expect miracles). It cools at close range and the clip is very practical since you can place it wherever you want. It also seems durable; my 1.5-year-old son has already thrown it about 10 times and so far it's holding up just fine.

Small but does the job just fine on a desk for hot days and for anyone who can't stand air conditioning or a larger fan close to their face when doing office work
