receiver failed at first start. goods supposed to have a 2 year warranty. seller doesn’t want to send a new one at his own expense moreover 60Hz receiver ordered, 50Hz receiver sent resulting in a 20% increase in fan speed thus at fan speed 4 the fan vibrates and some times stops as if it has reached maximum speed. so good design good functionality on the paper only

this fan is very good quality and seller is good communication and respond,
