The fan works by sucking in air from the base and enhancing its force as it is pushed through an opening around the ring. Like conventional fans, it also has an oscillation button, variable speeds, and a tilt feature.
Online reviews have been mixed. While some praise its sleek design, others compare it to a salon hair dryer or Rosie the robot from "The Jetsons." I expected it to be quieter than a conventional fan, and it is slightly quieter than a small Allaire fan I purchased at Restoration Hardware for . But at higher speeds, the Dyson is not whisper quiet.
