I purchased from market on nov 2017, but this fan producing low noise from march 2018, and fan switch off time was within 1 minute, and I didnt now earlier due to one ball bearing was fault within manufacturing defects. When feb 2020, that fan was sent to repair, then electrician told me that incident. He repaired my fan till now that fan is working very well. So, he told me that fan has excellent copper winding so that fan can run minimum 10 years
