I received these the other day, and just plugged one in a moment ago.
Works pretty well, similarly to my Comfast AC650 + BT dual-band AC wifi with single antenna, driver free.
You plug it in for the first time on a "virgin" (driver not installed before) system, it shows up as a CD-ROM, you double-click it. For this one, I had to navigate to the Windows directory then run the WifiAutoInstaller.exe. UAC prompt, OK. Then it installs the driver, and restarts the adapter, I did not have to remove it and re-plug it in. Select your wifi network, off you go.
I have an AC router, my AX 160Mhz router is unplugged, so I cannot test the max speed of this adapter. Although, it's 2x2, and doubled my upload speed to 240Mbit/sec.
Edit: I have a pair of routers arriving soon, some today, some in a week, from Newegg. Should have a GT-AC2900 ROG RAPTURE router with 160Mhz channels to test today, and a GS-AX3000 ROG router to test soon.
I'm kind of curious if this little USB adapter supports 160Mhz 2x2 or not. I'm guessing, probably not, but if it does, that would make for some killer performance.
Edit: Got my GS-AX3000 Asus Wifi 6 router installed. It supports both LAN and WAN 1+1 aggregation, as well as also WAN fail-over (but not both at same time, I don't think). Connected to Gigabit FIOS, it has built-in wired speedtests powered by OOKLA, and I get 800Mbit/sec down.
But after installing the updated drivers to get the Fenvi AX1800 USB3.0 wifi working at all in my Ryzen 3600 / B450 desktop in the other room, the most that I get wirelessly from this router is around 330Mbit/sec down, and 300Mbit/sec up. I get similar with an up-to-date laptop. I have 160Mhz channels enabled on the router, but I don't think this USB client device can utilize them.
