It is incredibly powerful, but also incredibly noisy. Both apply even at the lowest setting. In another review, someone writes "it's not suitable for sleep". It's not suitable for general home use, I would say. Its noise is equivalent to a kitchen hood. It reminds me of the fans that cafes have... maybe it's intended for a different use, outside of indoor spaces.
I have the same one, from the same company, in a wall version on the balcony and the noise bothers me significantly less in that environment.
Here I should mention that the other one that stays outside all year round with just a hood still works properly after 5+ years.

So I have it for two years in an office, inside a production unit where crazy temperatures are developed and honestly I love it. It distributes the air, minimal noise and works 10 hours a day. 4 stars because it is not silent. Otherwise, it is worth it.

It is too powerful and noisy like an airplane. It is not suitable for sleeping due to the noise and excessive power, even at the lowest setting. Forget about the third setting because the air feels like a helicopter taking off. I only bought it for workout time.

Update 5/10/2020: After 2 years of use, only 4 hours per week for 2 summers (approximately a total of 200 hours), its performance has significantly declined. I lubricated the bearings, but it didn't improve much. It now produces much less air than when it was new. The motor overheats, resulting in hot air being blown out.

Update 28/6/2021: It burned out during the hot days with very few hours of use. The motor was overheating, and you couldn't even touch it.
