Very powerful, I bought it yesterday after a long search. The airflow is good, at level 1 it blows quite a bit, at level 2 it almost blows the curtain vertically. At level 3, just leave it, of course it makes a little noise but it doesn't bother me. What I want is for it to blow well, it doesn't have vertical tilt but only horizontal, of course I don't want it to rotate, I want it to stay fixed in one place. And something I forgot, something that is not mentioned in the description, IT HAS A METAL BLADE, that's why it is very powerful. If the noise doesn't bother you, get it with your eyes closed!
