http://tinyurl.com/glvmj3j Secret deals at GearBest.
I have received my order and package is ok, but device do not charge. LEDs don't light when I try to charge. UPD: After a few weeks of the Gearbest trial on my case they decided return my money to Geabest wallet, so I bought two Mi Band 1S. They are working pretty well for cheapest tracker with heart-rate ever!
