Sorry I don't do youtube (my bandwidth costs), but did a search for that product... not results = no promise
I have the vuzix VR920.. and these are my personal thoughts about it.
- optics are mediocre
- the head position sensors were not engineered well resulting in reference instability.
I'm a hardware 'nut', if you wish and I stripped my VR920 to check out the inner workings. I really thought that they did half-a-job on this one.
The optics and lcds came in a module, and they added their head sensoring thing to it.
My impression is that they did not know what they were doing, as there were much better position sensors on the market before the VR920 was announced.
With their new products they might have learn't a few things, but I'm not holding my breath.
