I purchased a cheap chinese phone. Overall it was a good phone, but it does lack the build quality. The phone didnt last that long, and it didnt really save me much.
The elephone was similar to what I ordered. Check out GearBest if you are going to order a chinese phone, could save you a few quid.
Decided to buy a better cheap phone to replace it and went for the OnePlus 3, at £309 its not cheap but its half the price of the iPhone and s7, and similar spec. I would recommend it. Fully charged battery in an hour, lasts 1-3 days. Love it even just for not having to worry about keeping it charged all the time.
As above check out the Xiaomi Mi Phone. Xiaomi are massive in China, their version of Apple.
