The fan barely moves any air at all. You almost can't feel it. I used to have a cheap USB fan with cheap foam blades and it created a great little breeze (I'm still trying to find where to buy another one of those), but this fan does almost nothing.But what it does do is shine a *bright* white light at your face. Why would you want that from a fan?? Ugh.It doesn't let you turn off the light, but it does let you turn off the fan. So I suppose this is useful if you want a bulky USB light.
