There is a difference in the technical specifications as advertised online compared to those printed on the packaging as well as the official website of USHA fans. For the exact same model, the airthrow value is 85 cmm as advertised compared to only 67 cmm as per USHA fans website. The box/carton has no indication of the same. Not sure which values hold good. Delivery and packaging was excellent and timely. Overall good performance for the price.
