This is an imported Microsoft HoloLens (1st generation). I used it a few times for development around 2018, but it has been in storage since then. I have reset it to its factory settings for this listing. I believe all the accessories are included, please check the photos. Contents: * Microsoft HoloLens unit * AC adapter for charging * Micro USB 2.0 cable * Carrying case * Replacement nose pads etc.
