OnePlus One review: A $300 phone that looks, feels, and acts like a premium device (Brad Molen/Engadget) http://www.engadget.com/products/oneplus/one/
The respectable people from Engadget have given a (p)review of the OnePlus One.
It seems that it lacks a little in terms of camera performance and audio output volume. It could of course hardly be better in every respect and cost only half of what competitors charge.
Still looking forward to trying it myself.
