The fan is mediocre as even though it is 50 watts, it is not particularly powerful. In order for it to have some performance, you have to put it on 2 or 3 where it is also noisy. In general, I suggest avoiding it.

Compared to other 50W fans, it is very weak. Speed 3 is equivalent to performance at 1. You have to be very close to notice any airflow. I do not recommend it...

The purchase of this fan was a mistake and I will explain why. The 30 cm diameter covers minimal space. It barely covers two people in a bedroom. It does a decent job assisting with air conditioning because it blows the cold air that sits on the floor. It is also lightweight, making it suitable to take with you camping. I have two other standing fans at 50w, similar to this one, that operate at the first speed like this one does at the second speed, and with less noise. The noise is significant and this is again due to the 30 cm size. Conclusion: Get a standing fan at 50w or preferably at 60w to cool down.
