Review on Xiaomi Mijia Floor Fan (JLLDS01DM), white by Felicja Kula ᠌

The motor itself is silent. But here the screw / propeller is eight, since there is a beating on the stem itself! because of this, there is vibration in two planes, because of this, the entire body vibrates, and most importantly, this vibration of the screw creates a pulsating low-frequency sound, like a working shunting electric locomotive (whoever heard at the station will not forget). If you turn it on in silence - after 15 minutes you can already move in phase from this sound .
