Had mine since October.
Positives:
Screen is lovely.
64 gig so no storage problems
Essentially a mini tablet in your pocket.
Dual Sim as mentioned above.
Over all it’s a very good phone.
Solidly built, it’s taken a couple of serious tumbles and survived.
Negatives:
It can be laggy at times and need a reboot (part and parcel of getting a cheaper option in my opinion).
It chews through battery and lasts me a day at most, as in overnight charging is required.
It lacks NFC that the One plus one had.
It seems like the screen is marked easier than the opo too, scratches and even an impact mark in mine from somewhere.
Overall though for the price I think you get a great tool, it’s less of a phone and more of a device, use mine for all sorts and would buy another from the brand.
