This is a very valuable VIVE PRO EYE full set. I was using it without any problems in VRChat. It is equipped with Tobii's eye tracking, which boasts the highest accuracy. All functions, including eye tracking, work without any issues. ☆ Although it's an older device, it's in pretty good condition. ☆ There are no missing items, and all the genuine parts are included, which are very rare. I think this is a rare item, so please consider it. ※ You can add 3 VIVE Trackers 2018 for an additional 20,000 yen! ※ Please note that the original box is not included. Thank you. #EyeTracking #EyeTra #VRChat #VRC #HTC #VIVE #PRO #EYE #VR #HMD
