I am yet to open and operate my Z5 Premium. But hopefully all will be good.
my main disappointment was that Becextech implies it is in Australia, when it appears it is not. However, it only took 3 days to receive my phone shipped from Hong Kong. So i am impressed with that. Lot of chinese on the box and instructions, so hopefully my smart phone smarts out does this.

Didnt get my free gift... but ya get that.

Approximate cost: $900
