Review: Works as expected - Plug and play, working flawlessly. Getting 2.5GB speeds.
Review: Works right outta the box... - I've been using this NIC for the last 2 months on my UDM-SE without any hitches or glitches. Although I am not a network expert, and I rarely play games (only an occasional Elite Dangerous or NMS round), I have never had any issues with latency or dropped packets, or anything that would bring attention to the NIC. It's a fine card, especially at this price, and I would recommend this upgrade as an entry level NIC to anyone wanting to make use of your ISP's higher level speeds without breaking the bank.
