Plug and play. No issues - worked out of the box. Firmware was also updated to the latest version when I pulled the card out of the box. I also really appreciate support from FS during my shopping/decision making. The experience was flawless.

Prices/quality are great, support as well. Nothing to complain.

The product did everything it stated, it would Work Great !!

works perfectly, delivered on time and packed perfectly with no damage. Effortless install under Windows 10

Have bought about half dozen, and all work as expected. This time very fast delivery too!

Plug and play, no issues, in a server running Proxmox VE 7.2-11, connected to a Mikrotik CRS518-16XS-2XQ-RM with FS generic 25G DAO.

I have bought 2 of these and have no regrets. I've pulled off 10+ gbps speeds on both of them. It's a great investment.
