They plug into your usb port (if you got a free one), have a bendable arm and the fan is cloth so you dont chcp off your finger.
It works really well for cooling off my laptop—I have a dell latitude and it gets really hot—i just position the fan to blow into/ on top of the pcmcia port and it works nice.
Only downside is an annoying “buzz” of the fan.
It probably works well to to use for actually fanning yourself, but i have an air conditioner for that.
