I am selling this item because I purchased it but never used it. It's a high-quality wired LAN adapter made by uni. It's perfect for locations with unstable Wi-Fi or for thin laptops without LAN ports (MacBook, Windows, Surface, etc.). • High-Speed Transfer: Supports USB 3.0, enabling high-speed communication up to 1Gbps (1000Mbps). • Easy Connection: No drivers needed; just plug it in and it's ready to use. • Design: Made of aluminum for excellent heat dissipation and outstanding durability.
