HTC VIVE Pro 2 HMD (Head-Mounted Display) standalone model Includes two base stations and two VIVE controllers. The second and third images show accessories related to the base stations. This is a complete set that allows you to play VR immediately if you have a computer. Recommended for those who want to use VRchat or play VR games. The goggles have only been used a few times since they were purchased new, so I think it's a great deal.
