I bought iPhone 6plus and heard some rattle noise while shaking side wise and returned. The have replaced another one and it was not detecting any network and returned again. It took more than a month for these two.
It seems faulty products are selling without any proper inspection even though they claim they are selling individually inspected phones.
SO NEVER BUY WITH BwcexTech and BETTER GO WITH SOME OTHER TRUSTED.[Redacted generalisation]

Approximate cost: $750
