Bests & Worsts Reviews from Amazon

There is an awful whine/hum/grinding noise when this fan is running regardless of what setting it is on. Annoying enough to where we won't keep it on at night. If this is a QC issue than we received a faulty product and will need a replacement. If this is a design flaw we will be returning the fan as it's a deal breaker. The old version of this fan is great and makes little to no noise while running. Not so "quietset" after all... video attached
