Not tried the OR yet, but I did try a VR head set something like it a few years ago at a flight sim show, I could not get it off my head fast enough, it was like feeling vertigo and inducing a headache from the moment I opened my eyes.
I was so disappointed as I would have loved a system like that, but after that experience I would have to try OR before I would even contemplate about buying it.
My eyesight is marginal and out of alignment at best, and is why I fly sims and not a real aircraft.
I have had 3 operations to keep my eyes under control and last time I was told that it would have to last me until I get my own personal wooden pod ;)
