### ⭐⭐⭐⭐⭐ Easy to use and negotiates 2.5 Gb
*by Z***Y on October 4, 2025*

Plug and play no issues on Windows 11. Didn't have to find drivers or anything.

### ⭐⭐⭐⭐⭐ Boy, did this up grade my machine.
*by A***E on April 6, 2025*

Boy, did this up grade my machine. I have just gotten true fiber installed to the house and found that the promised speed just was not there. The technician told me to turn up the speed on my PC. It was then that I found out that my mother board was the speed limiting issue. Once installed - wow, smoking fast. Compatible with my windows machine and software. Installation was easy - software/driver took a little time but all the work was well worth it. So far, no function or stability problems. Over all I am pleased with the purchase.
