These Optimus Fans are made so cheap and with such bad quality that it doesn't last more than 2 weeks to a month. Additionally, the fan has bad smell that comes out from the motor area while running. The oscillation gives problems, it clicks and even stops working most of the time. The oscillation also jams and stops the fan. Overall, bad quality and poorly made. Waste of money. I would not recommend this to no one who is looking to buy a good fan. Please don't waste your money buy any models of the Optimus fans. If you are looking for well made fans go with Bionaire, Lasko or Kenmore.
