This fan makes a loud rattling noise which is very annoying. The breeze it produces is pathetic and barely noticeable, unless your face is right next to it. Frankly, I'm flabbergasted by the other reviewers here — are we even talking about the same product? In 14 years of using Amazon, this is one of the worst things I've ever bought. Sat here in my flat, sweltering in 30°C heat, and this fan is next to useless.
