Did they say why? Did it make them sick? Did they not like the games? Was it too expensive for the content that was out?
Too expensive for the content that was out was the largest complaint, since they returned/sold it pretty early into it's life. I have a handful of friends who are really into VR, but iirc they've got Vive/Oculus and are thriving on Steam's library of available of VR games. Price difference is crazy, though.
