This is a tool for smart glasses, specifically for XREAL. I used it without any issues with the air2 PRO. It doesn't include the box or instruction manual. After all, XREAL smart glasses are best with the expansion features provided by BEAM. I used features like screen space pinning, Netflix and Amazon Prime app usage, and WiFi/Bluetooth connectivity. There is a thin scratch about 10cm long on the back. Other than that, there are some minor scratches from normal use, but they are not very noticeable.
