I’m using the fan in my exercise room about 8 ft from my treadmill.  Comes in three speeds but truthfully, the fan is incredibly mild and I use it on the highest speed.  The nicest thing about this little fan is the quiet, so if you intend to use it to sleep, the fan is perfect.  For the price, a very good buy, but don’t ask for a cyclone.  Also does not oscillate but can be manipulated up or down. Good for the price
