The purchase date is mentioned on the photo memo. I got it at this price because I bought it from a well-known shop in Rifle Club Market. Since the date is not written on the warranty card, you can avail of replacement/warranty benefits at any time. The reason I bought this fan was that its airflow (330rpm) is higher than other fans, but after bringing it home, I found it doesn't adjust to the room size, so I want to sell it. It is completely intake, unused, and a brand-new fan.
