I bought this Oneplus One mobile through free invite from Oneplus itself. I gifted this mobile to my wife and she loved it very much.
Quality of the back camera is bit disappointing but I feel there should be some configuration issue. She is using this mobile for more than a year without any issue. This is really an excellent phone for this price.
Pros: Big and still comfortable screen size, Full HD Display, OTG access, value for the money, Surrounding Sound, High Volume, 64GB internal Storage
Cons: none really
