I was looking for a good fitness tracker that is fairly cheap and I stumbled upon the Xiaomi Mi Band.
This is one of the lowest prices I could find to get this fitness tracker in Australia.
So if you're looking out for a decent beginner-level tracker, this is one of the best value-for-money wearables to consider.
BTW Battery is supposed to last at least 30 days!!!
It only comes in black, but you can purchase additional bands in various colours.
$2.19 from ebay: www.ebay.com.au/itm/New-Ornament-Replacement-TPU-Wrist-Band-…
IT IS ONLY COMPATIBLE WITH ANDROID
edit; I've been told it works on iPhone via the Mi Fit app - thanks bethanyrae81 (though with less functionality)
Apparently there are hacked APKs which allow you to receive notifications on the tracker from apps like Facebook.
Otherwise you cannot
Also I just realised that you can get a bonus 4.80% Cashback if you make a purchase on Banggood through Cash Rewards!
Just had to charge mine after 61 days, problem was remembering where I left the cable
