Can't really review as this device properly as it doesn't come with the sensor that provides the head tracking support. The only thing in the box is the headset and it's not even recognized as a device by SteamVR so the only function it serves is as a secondary monitor (and a very poor one at that). The instruction manual is all in Chinese and as far as I can tell the software that would allow it to function is not currently available from the manufacturer. The product box was not sealed and plastic protection covers appeared as if they were removed already and replaced.
