It does what expected. It's got some power and creates very good wind when on full blast.
On full blast it's not as quiet as the adverts make you think but when it's on low level it produces enough wind to make you feel comfortable and you can hardly hear the fan. I don't like the sleep or outside function as it drives me nuts having the speed and therefore sound, changing all the time.
I used it on full blast to dry my clothes quicker. Very helpful.
I have two of them and I can recommend them.
