Nothing like the pros in the field like HTC or Oculus. Very pleasant headset to wear for hours on end. Quick and easy setup system. Reliable transmission of controllers and headset. The "TrackEyes" system is very good but no game uses it yet. Too bad the small 110° focal length takes away from the immersion. The Oculus controllers are much better. The lenses are not bad but not yet at the top. When the contrast is strong (white under black) the reflections are quite apparent on the lenses.
Pro
System of fixation and adjustment of the head at the top
Good lenses but there is better.
Headphones directly integrated
Nice weight when the headset is well adjusted
All-in-one cabling very appreciated
Contra
2.0 sound system... 5.1 would have been a minimum
Price a bit expensive for a technology not yet exploited by games
