I bought oneplus one on it day of launch. I got it delivered with 1 day thanks to Amazons super fast delivery service. I got a charger cable, extra sim adapter for nano sim and charger. It came with cm 11 and later it got update to cm 12.1s with lateat android lollipop 5.1.1 and company has promised update to marshmallow. It had 64 GB from which around 54 GB was usable. The pone dint lag while playing high end games.
Pros:
Value for money.
Good storage capacity.
NFC.
Cons:
Battery doesnt last for too long.
Gets heated up after long time use.
It is best budget high end phone.
