## Customer Reviews

### ⭐⭐⭐⭐⭐ Great network card
*by Z***S on January 21, 2026*

Excellent controller. Worked out of box without installing any drivers and was detected perfectly by the bios on my Supermicro motherboard with full functionality.

### ⭐⭐⭐⭐⭐ Works better that I even knew
*by C***N on December 3, 2025*

This board, brings 20g to my computer and I must say, my computer has never behaved so smoothly with this installed. No more bottlenecking usb connections. Ndi forever!

### ⭐⭐⭐⭐⭐ true 10gb nic
*by B***N on January 12, 2026*

Inexpensive 10gb network card. Full 10gb in x4 slot. The heatsink is bigger than most other cards, I have mine in the bottom slot on my matx motherboard in an Asus AP201 and have Lian-Li P28 fans on the bottom, these fans are 3mm thicker than standard fans, the heatsink presses into the fan a bit and made installation difficult. I tried a different brand 10gb nic that had a smaller heatsink and that one fit without issue but that card wouldn't link at PCIE x4 so it didn't get 10gb. I'll probably sand down the heatsink a bit so it's not pressing into the fan.
