I received it on 23/08/23 and assembled it in less than a quarter, without even reading the instructions. It is very easy to assemble and very powerful. I placed it in the living room, which is over 40 square meters, an open space together with the kitchen. It makes a lot of noise in the bedroom. As for its lifespan, only time will tell.

June 2024
Second week of June with temperatures in the forties.
I put it in the bedroom, which gets sunlight from noon until sunset, because some other smaller ones we have don't do much.
It cools the 25-square-meter room quite well, but from the second day of operation, the rotation function doesn't work and the fan head remains in the same position.
I also raised the stand a bit and it got stuck. I can neither raise it nor lower it anymore.

The fan worked last year, during the last days of August and a few days in September, which means less than a month. It is unacceptable to have such damages.

In 2023, when I bought it, I gave it 5 stars. Now I am reducing it to 3.

Okay guys, the truth is that it is very powerful and worth the money. However, I don't think you can sleep while it's operating, it makes a lot of noise. Even at the first level, it sounds like a helicopter.
Oh! and it's huge.
Update: After 15 days of use, one wing came off. Guys, it's not worth buying. It only lasted 15 days and didn't work much because the first level was too powerful and had almost no difference from levels 2 and 3.

Pocket tornado.... The first level is very powerful. On the third, it takes you and lifts you up. Almost slightly professional. Assembly requires a little experience or help from others.

This is a powerful fan. Very satisfied with its performance as well as its price. There is some ambiguity in the assembly instructions, but it can be overcome because it has few pieces to assemble. The noise is satisfactory in relation to the motor power. The base appears to be more reliable compared to those in a cross shape. Overall, the quality of the materials for the price seems fair.

I will recommend it to friends.

I deduct one star because in the summer of '20, the power switch broke. Specifically, the cap that rotates the motor shaft got worn out, and since then, I have permanently kept it in the low position. I do not believe it is due to my own misuse.

Regarding the noise that I saw in other reviews, this should be expected because it is a machine with high speeds even at low settings, combined with the design of the blades. However, whether it is worth sleeping in a bedroom with this particular fan is subjective, whether it is for the noise or the strong airflow.
