Lasko had to send me the base.  It was missing from the box.  I wrote to them, got a base from them for a different fan.  I bought a part and set this fan up.  I was extremely disappointed.   All plastic parts, poor quality.  It literally fell apart in 20 minutes of using it.  Wrote Lasko, they said I had to return it to wayfair and no response.  Awful experience.
