VIVE Tracker (Ultimate) 3+1 Kit Pairs with VIVE XR Elite headset and controllers for wireless full-body tracking. Includes 3 VIVE Trackers (Ultimate) and 1 VIVE Wireless Dongle. No box included. Please feel free to ask if you'd like additional photos. I purchased these for a review, but I already have a Lighthouse environment and have confirmed their performance, so I am selling them. I used them in VRChat and they worked without any issues. Due to the high price, returns are not accepted. Please understand this before purchasing.
