Even though these fans are astronomically expensive, I must say after having one you will never want to go back to a regular fan. These fans are a masterpiece of engineering.
I really wouldn’t waste money on these Dyson’s fans. A friend bought a few for his house, bragged for England that he owned 4 Dyson fans. Me, I had proper air conditioning installed and I still saved money compared to buying 4 Dyson’s fans, my home is a lot cooler than what these fans could ever achieve and I can run it all night if I need to and still hear a pin drop.
