This is idea for what I'm using it for.  It goes in my little girl's room.  It's tiny - but it really does generate air flow!  I was surprised, as I wasn't expecting much, and it wasn't expensive.  But it was a bit of a challenge to assemble, due to coming in so many pieces. After I got it together, though, it was a breeze to hang up (not heavy at all) and looks so cute in the room!  Her room is only 8 by 10, though, so I'm not using it to try to generate air flow for a large room. For this size room, it works just fine.
