For £23.10 ex‑VAT, this is the kind of “get me online quickly” adapter I actually don’t mind recommending—especially if your users need a reliable wired link without messing around with docking stations. The 2.5GbE part is the big value: it’s a noticeable step up from standard 1GbE when you’re copying files between office systems, syncing big datasets, or your switch/storage gear supports it. In day-to-day B2B use (Windows laptops, Macs, occasional travel setups), USB Ethernet adapters like this are great for keeping things stable and predictable compared to flaky Wi‑Fi.
That said, I’d only buy it if you *expect* to use it in environments where 2.5GbE is actually beneficial. If most of your network is still 1GbE, you’re paying for a capability you won’t fully see—though it won’t usually hurt performance, it just won’t deliver the upgrade. Also, don’t expect miracles on heavily loaded or poor-quality USB ports/cables—this sort of adapter is as good as the host/controller it’s plugged into. Overall: good value for small offices, remote workers, and anyone who needs a dependable wired fallback that’s easy to deploy and replace; not worth it if your network is firmly 1GbE and you’re buying purely for “future proofing.”
