If it was a little quieter on scales 3 & 4, it would be ideal. However, it doesn't prevent you from sleeping, for example.
Also, I don't know how it will perform in spaces larger than 20 sq.m. that I use it in.
I think it will be fine up to 30 sq.m.

Very good fan! I bought it mainly for its design and because it stands out from all the other classic fans on the market. Its construction quality is excellent and contrary to some reviews that say it doesn't have good performance, I find its performance very satisfactory.

Quality construction, excellent design but in terms of functionality, it falls far below expectations. Unfortunately, it is not worth its money.

1. It is something between an air conditioner and a fan (as we know it), I prefer it over the air conditioner because it provides natural coolness.
2. It cools the space by directing the air upwards, so it doesn't hit you.
3. Nice design.
4. Quiet.

This specific fan is very efficient and user-friendly. Its design is beyond the ordinary and the build quality is excellent. It is not a typical market fan. It has three height adjustment options and four speeds. Its performance is very good because the air is shaped by its blades to create a pleasant feeling of coolness in the room. You can turn it in many directions, even vertically upwards. We have it in a bedroom of about fifty square meters and we sleep with the second speed. Overall, I am very satisfied and I highly recommend it.

It is a fan different from the others. It is quiet and the air is evenly distributed in the space, whether it is a smaller one like a bedroom or a larger one like the living room. Its design is modern. Overall, it is a very beautiful and unique element in a house. I would recommend it.

Do not bother. I cannot understand what difference it has from a classic fan with horizontal adjustment. It is relatively noisy at position 4 (high speed) while in a room of 18 square meters, the air circulation for which it is famous is not something special (and again in the noisy position 4). I tried to change its position and height but with little result. If someone tries it in a doghouse, they may be satisfied.

I have it in the bedroom where at the first level it is silent as if it is not working. It is a fan completely different from all the others in every aspect. Due to its ergonomic design, it evenly distributes the air throughout the space, giving the sensation of a pleasant and gentle breeze. In terms of design, it is very advanced. I would say a work of art. I am thinking of getting one for the living room

I saw it at a friend's house and I was impressed. We also bought one for our living room because the air conditioner was bothering us. Absolutely silent, good build quality. Very unique design that enhances our space. Its price is quite high, but it's worth the money.
