      Item as described. It's labelled correctly and it reports correctly in my server. It works correctly with MFT. I was able to update it to the latest Mellanox firmware without issue. The LEDs work. The thermal paste was old, but that was expected; repasting was easy-enough. Item arrived well-packaged, and included both brackets. I suspect this is NOS rather than used, as it looks brand-new.

      Item was in really good state might as well have been new. Surprised me to see the thermal paste was still very liquid, maybe a repaste or the cpu just doesn't get too hot. Tested and works fine, at least for 10G SFP+. No complaints here

      Everything works like intended, no problems under Proxmox 8 and with Ubiquiti 10/25Gbps DAC connected to Mikrotik switch. NIC was packaged in plastic "box" with low-profile adapter in separate compartment and was in superb condition.
