Yep, That's me, wearing the Bigscreen VR headset today. I want to share my opinion.
The size and the weight is better than any other headset. There is no grid visible. This is what VR should be. A view with no pixel grid visibility. The pixel density is REALLY good. I think the FOV beats the Quest series a bit.
There is no cameras, this is the Version 2. Unbelievable. The lenses can have your vision fixed, so no need to use glasses. The cushion is tailor made 3D-printed, so you will have to scan your face with Iphone or Android. No seams.
Highly recommended. I have zero connection with these guys, paid for this before the release.

Expensive, yes, good... well, worth it, if you look for perfection.
