Saw the 2nd gen MotoG deal so decided to post this, this phone has better specs with the same price tag. BenQ is a pretty good brand too (no comment on Kogan itself though).
As it's essentially a Taiwanese brand, more reviews and unboxings can be found on TW websites, you'll need Google translate if you can't read T-Chinese: Here, here, and here
Dual Sim? Probably never get a lollipop upgrade eh
