This is a set of two HTC Vive Base Station 1.0 units. The items included are everything shown in the images: two base stations and two AC adapters. As shown in the images, they power on and display the operating status. They were tracking and working normally until recently, but I have sold the headset, so I cannot confirm their operation at this time. One unit has a defect described in the following URL, which I have self-repaired: https://note.com/enlil/n/nf9735552d3e0 Due to the above, please consider these as junk items.
