Works much better than the cheapest ones
I thought that I was wise to buy the cheapest (£12-15) version of the 2.5Gbs USB adapters. I thought that they have the same Realtek chip and it is just the branding what may differ. I had a wild ride with those cheapo adapters. They randomly disconnected or Linux could not even recognise them ("bad cable").They continuously reset themselves, causing the device disconnecting and appearing again on Linux. Forget about them.This adapter so far just works as I hoped it will. No disconnection issues.Connected them to Synology NAS devices and with the extra driver, they works stable and 2.35Gbs speed or about 250MB/s NFS writer speed are achievable.It works on Linux (Proxmox) and it operates stable. (Not like the cheapo version).Windows works as well, but surprisingly it works worst on Windows than on Linux!I tried this unit on a modern HP laptop and it could achieve an iperf3 test around 1-1.5Gbs. I thought maybe there is some constraints on the shared USB bus. But, on Linux, iperf3 runs on 2.35Gbs. Okay, it is maybe one device, so I tested on others. Similar experience. I tried to update the driver, but no real speed improvement. Luckily Windows was not my main objective.I was not super lucky with OPNsense. The device recognised the adapter and it works with it but it felt like that, even on the switch, the negotiated speed was 2.5Gbs, it may stuck on USB2 speed on my box as the max speed was around 360Mbs. You may be luckier, at least it works and stays stable.After all, I will order these again if I expand my 2.5Gbs network with new devices.

Does what it says on the tin
Solid little adapter, and the newer lower power and heat version to boot. Consistent symmetric 2.5Gb without heat build up, no issues. So good I bought it twice.

Does the job
Little bit more expensive than others but far better quality and well made. Works well no issues would recommend.

It works with Synology NAS
Great item, bought to use with Synology to upgrade to 2.5gbs, works great connection to my new deco router, I will buy one of these for my PC to make transfers faster.

Fantastic, plug n play 2.5GbE
Plugs and plays on my Win10 Lenovo x390, no drivers required and immediately connected at 2.5Gb/s.Can't comment on the value as there were cheaper models available but I felt safer going with a known-brand.
