The fan comes with multiple functions. You can change the mode (how the air blows); speed; turn angles (0, 60, 90, 120, 360). You also can put the fan in auto mode, which lets the fan adjust the settings as needed. The fan also has a sleep mode, which runs the fan on the slowest speeds.
On the downside, my children can operate and unplug it. They also un-leveled the base. Thank goodness for the screws and it went back in place.
