expired Xiaomi Mi Band 2 US$18.19 (~NZ$25) With Coupon @ Gearbest
The Xiaomi Mi Band 2 is down to the lowest price I've seen, now around NZ$25 shipped. Use the code MBANDUK to lower the price. It looks like Banggood and Gearbest is having a little price war @ HUKD, check out both links below.
I'm wearing one now and the battery life is fantastic, although the heart rate monitor is both a bit slow and inaccurate.
