    NIC works as expected, tested with 1Gb and 10Gb and works great with both speeds, heatsink gets a little hot sometimes but it haven't caused any issue, also great packaging. I had a little delayed on the delivery but I'm very happy with my purchase and definitely will be buying more to my servers.
