Mine just arrived one hour ago.
I play DCS. It is marvelous. Bright, crisp, fast.
Better (lot better) than my former Oculus Rift, and slightly better that my former Pimax B1 (more bright, and it is 90 HZ indeed).
My IPD is 63. I heard that this is exactly what Lenovo Explorer wants. So others might have problems with it.
Little blurry on margins, I guess exactly how FOV-eated would look like.
Don't have time now, but I might make some vids on how things look through lens. Never seen on youtube this yet.
