### ⭐⭐⭐⭐⭐ Works better that I even knew

### ⭐⭐⭐⭐⭐ Great Value - Works with Windows 11

Works with Windows 11 and is a great value. Must download drivers separately from the internet before to get Win 11 to work easily. There is a large thread about this on reddit. Item was easy to install and both normal and half height covers were included.

### ⭐⭐⭐⭐ Great Card on an Older Chip, Need to Manually Install Drivers
*by C***S on May 26, 2025*

This is an older chip as others have mentioned, but it's still plenty capable of the advertised 10gbps speed. The price is on point, being among the cheapest options for 10gbps networking. There's no issues with build quality or compatibility that I've run into. The one thing to note with compatibility is that Windows does not include drivers for this device. You need to install them from the disk or from online before the NIC can be used. I've taken to adding the driver to the USB thumb drive I use to reinstall Windows. Otherwise, there's no bloat. Installing the drivers is painless, and quick. After that it works like any other network card.
