price:AU$6.45 / US$4.99
Limited to first 500 stock , 3 times per account, AU and NZ only.
The first code is for the Original Xiaomi version, the second code for the Xiaomi Aqara version here: https://www.gearbest.com/access-control/pp_626703.html (second code used up)
I don't know of any differences between the two except design (and 1ct), if you know of any, let me know in the comments.
You will need the Xiaomi Home Gateway to make use of these.
Both codes are limited to 3 times per account, AU, NZ only. 300 units Original, 200 Aqara.
Check out in AUD, the conversion Gearbest uses is better than the official USD rate (which would cost you about AUD 6.50).
Thanks to the Gearbest rep for the codes. Very responsive and always willing to knock a $ or two off.
