Without it, these HMDs are not functional devices. With a proper, stable mount, it would be a 4 or possibly 5 star device. Will update after I’ve tested the headband mount.– Update 2019/04/10 –Received the headband mount, which was not as pictured. It’s just the hat mount, along with a cheap headband, and doesn’t work very well.
