Product Overview
AI-generated summary
For £22.75 ex-VAT, this is a sensible “get online fast” adapter if you’ve got a laptop with flaky Wi‑Fi or you need a reliable wired link in meeting rooms, warehouses, or client sites. The real-world win is that it’s genuinely convenient over USB‑C, and the 2.5GbE support is a nice bonus if your network gear and switches actually push beyond 1GbE. It also tends to be more trouble-free than cheap no-name adapters—StarTech are usually consistent with drivers and behaviour across Windows and macOS.
That said, I wouldn’t buy it for high-throughput production work. USB Ethernet can be perfectly fine for file shares and day-to-day use, but it’s not the same as having a proper internal NIC, and 2.5GbE won’t matter if your router/switch is still at 1GbE or if the rest of your setup can’t feed it. If you’re buying because you “need 2.5GbE”, make sure your network path supports it; otherwise you’re just paying for features you won’t use. For most office/field-business users who want dependable wired networking without docking, it’s a good value pick.
