Hello, based on the reviews (I should have to listen to the only negative comment that proves to be the most loyal to the proceeds received) and the reputation of the brand I bought this fan to put it next to my bed, being under the roof it is very hot at home. Good surprise in design and power but huge disappointment to the noise level. It is absolutely impossible to sleep with the fan on even level 1 and it is even embarrassing to watch TV (I have to go up one-third the sound of my home cinema to cover the engine of the fan). A purchase that I can only advise.
