I purchased this unit to upgrade my Wi-Fi from 802.11(n) to 802.11(ax) WiFi-6.
Reason was because it is compatible with my existing AMD ASUS PRO WS X570 PCIe-4 motherboard and exclusively Linux OS.
I have regained my download-speed to the limit of my NBN plan, which is only 100~108mbps.
I haven't tested it further. Impressions are that it is robustly made, only needs a PCIe x1 slot, and is working well.
