I got the chance to experience a BLDC fan, Atomberg Renesa 1200mm model, for a couple of days in my relative's house. Here's what I felt:
The speed and airflow aren't as good as traditional fans in top speed. In boost mode, the airflow is good enough. Noise isn't completely gone, it's like, maybe 50% reduced.
Convenience is great as it has remote. Overall, if high airflow is a requirement, I wouldn't suggest this one.
