Fast Fan and very convenientEasy to assemble with a screwdriver. It moves way more air than you would expect from a fan this size. My picture looks like the fan is stopped, but that's because of how fast the camera is. The fan blades are actually going so fast you can't see individual blades when you look at the fan itself instead of a picture. The base is built just right to reliably keep the fan from falling over from the force of the airspeed. I only use the highest speed, partly because I don't see much point in buying a fast fan if I'm not going to use its fastest speed, and partly because there isn't all that much difference between the different speeds anyway. All three speeds are way faster than most other fans. The one you see in the picture is being used for circulating the air from a room that has a window air conditioner, through the hallway, to keep the whole house cool from that one air conditioner. It's a relatively small house, so it doesn't really need more than one window A/C, and this fan is what makes that window A/C work well for the whole house. The instructions seem to be wrong about which speed is which. But that's easily solved with a little experimenting.
When I'm not using A/C, because of nice weather, I have one fan aimed out a screen door, and another fan aimed through the hallway towards the room that has that screen door. That moves air through the house so fast, I can arrive home in the evening then get rid of the heat of the day by running the fans for a few minutes. And on a warm night, I run them all night. I don't care about the noise, but some people might be bothered by it.
We hardly ever have nights so hot that an A/C is badly needed. These fans are perfect for most of the warmest nights around here. This assumes you live in a relatively small town where you don't have to worry about burglars coming in through your screens. Fans are better than A/C because you get fresher air through the screens instead of recirculating your air through your A/C.
One thing to always remember about using fast fans for comfort: The key to being comfortable with them is to aim them away from you, not towards you. If you feel extremely hot, aiming them towards you for a few minutes is nice, but you don't want to keep the air moving towards you constantly, because it's too fast, and will start to bother you. The best way is to aim them out some screen windows or screen doors, as that will cause a breeze to come in all the other windows of the house.
