Review on XDO USB WiFi Adapter: 1200Mbps Wireless Network USB 3.0 Dual Band, 5dBi High Gain Antenna - Windows 10/8/7/Vista/XP, Mac OS 10.9-10.15 Compatible by Jeff Ross

To be fair and honest I ordered this XDO which was offered by Revain, I ordered a cheaper version of the same device with two antennas. After trying both on a clean new machine, XDO wins. The difference was only $7, but it was worth every penny. XDO had a slightly higher value in the speed check (via steering). I would say 10% higher with a single antenna. Also, the cheaper dual-antenna version I tried didn't go well with my small microcomputer. Antennas interfere with other USB ports. So if you doubt it, just get XDO. Thats much better. Final thought: - Inexpensive - Single antenna, easier to place in tight spaces - VERY fast speed - No drivers required for installation (Windows 10)
