This is a full set for playing PCVR games. With this set, you can play VR using 3-point tracking. I am selling this because I can no longer play due to changes in my living situation. This is a used item, so no claims and no returns. Please refrain from purchasing if you are overly concerned about condition. - Model: VALVE INDEX headset, HTC Vive headset - Accessories: Controllers (Vive controllers) x 2, Vive trackers (2018) x 3, Base Station 1.0 x 2, various cables I was playing with this set until recently, so there are no issues with starting it up. I was using the Vive headset as a controller dongle and the Index as the HMD. It should be possible to start it up if you have a certain level of PC specs. Thank you very much.
