### ⭐⭐⭐⭐⭐ Great price for 10GBe
*by M***E on 28 June 2024*

Saw this 10gbe nic on sale here and grab 2 of them for testing. Upon receiving the items, it was well box and came with a low profile plate. Installed them on my proxmox server box and was detected without any issues. It's now been over a week and still working fine without any hiccups. Will definitely buy more when it comes back on sale but might be looking for a dual or quad next.
