I had a go at a demo model, they only had one VR card and some basic pre-loaded software, that said the effect is really good and it actually works but it does for lack of a better description feels heavy on the eyes when you watch it, the analouge nub thing is.. well actually it's all perfectly positioned except for one thing, the nub is used for camera control, so unless you can move thumb fast, your not going to be able to move your character AND your camera. Not sure what else to say, so ask if and if i can reply i'll do so.
