YouTube scam advert fan available on AliExpress for £16 
If YouTube adverts handed out awards for ridiculous marketing claims, this one would be taking home the trophy.
Behind all the flashy videos and miracle-cooling promises its a cheap fan that can be bought on AliExpress for around £16. The only thing that's premium here is the markup.
Yet another drop shipping operation relying on slick advertising to convince people they're buying some revolutionary product, when in reality it's an inexpensive import from China.
Personally, I wouldn't be comfortable entering my personal or payment details on this website. I'd rather spend £16 on AliExpress than pay several times more for what is exactly the same fan.
Don't fall for the hype. Save your money, ignore the marketing circus, and shop somewhere more reputable.
