Pls suggest BLDC Fan?

Just got my first BLDC suggested by @anmolbhard004
So far so good. Really like the sleep mode and ability to control a fan via phone (have a xiaomi device with IR)

Noise is absolute zero. I registered for additional warranty on website but didn't received any mail or SMS for confirmation.

ngl but atomberg created this bldc segment and other brands followed simply atomberg has clocked 1000 cr sales last financial year.
 
Do you have Inverter at home and connected this BLDC fan with inverter?
Just asking as I read that frequent electricity cut may harm PCB of BLDC fan and BLDC fan are not repairable.
Are you saying frequent changeover between mains power & inverter power (depending on whether inverter is pure sinewave or not) may also damage pcb of BLDC fan?
