Seems like a good price for a DC pedestal fan with 12 months warranty.
I'm not the biggest fan of purchasing a DC over AC for a fan considering the power saving is around ~15 watts if comparing 40cm pedestal fans. If using it for 8 hours a day a DC fan will save around 120w/hrs a day compared to AC. In 100 days of using it for 8 hours a day that's 12,000 w/hrs, or around $2.16 if paying $0.18 per kW/h. That's less than a $7 saving per year. A cheapo AC fan goes around $15 which is $40 cheaper than this cheap DC fan, which means a DC fan would take many years to pay for itself if caring about efficiency due to cost.
But if you still want a DC fan, $55 is cheaper than the Kogan or Xiaomi DC fans when on special. I don't think I've seen a cheaper DC fan if purchasing new.
