The Xiaomi USB Fan is selling for S$6.99 and is available in two colors, white and blue.
During the Lunar New Year 2016 sale which happens from 21st January 2016 to 22nd January 2016, the price of the fan became S$5.99 which is S$1 cheaper. It is not much but better than nothing.
I bought two Xiaomi USB Fan and shipping cost S$3.99. In total I paid S$5.99 + S$5.99 + S$3.99 = S$15.97.
I thought the fan is pretty gimmicky and weak, but it turns out to be better than I expected. The wind produced by the fan is pretty strong considering how small the fan is.
The fan blade is made up of hard plastic and hence touching the blades when it is spinning do hurt. So becareful and keep it away from young children.
