My unit came with the headband detached from the head mounted display. Particularly the left side. It leads mo to believe they sent me a returned product from previous customer, because my preorder came in sooner than August. I wish I could post photo because that would tell it all. I tried putting it back but it just breaks off. My problem is the 2 arms that holds the goggles that houses the chip, oled and etc, the left arm is detach and I am not sure if its designed this way. I know it allows some movement for adjustment. Please help.
