Works in Linux (Specifically Armbian)
Haven't tested whether it gets the advertised speeds because I don't really need those and likely never will. This is connected to a Banana Pi M4 Zero to act as the upstream wifi (internal wifi is configured as hotspot/AP). For that purpose, it works great. Plug and play and was immediately detected. Seems to be using a Realtek chipset internally.

—this is your "just get me online fast and cheap" nano solution.
Don’t let the size fool you—this nano adapter gives you dual-band WiFi (2.4GHz + 5GHz) with up to 650Mbps total bandwidth. It's plug-and-play on most Windows systems (especially Win 10/11), and drivers for macOS are available via download. Once installed, performance is stable for web browsing, YouTube, Zoom, and light file transfers. Perfect for: Upgrading an old desktop without opening it Replacing a dead internal laptop card A plug-in option for Raspberry Pi or mini PCs Keeping in your EDC tech pouch for quick fixes What I Like: Tiny footprint—plug it in and forget it Dual-band flexibility = escape 2.4GHz congestion with a 5GHz option Stable connection for everyday tasks—web, email, streaming Works great for light gaming or Zoom calls, no dropouts in my testing What Could Be Better: Not ideal for heavy gaming or large file transfers—this isn’t WiFi 6 Range is limited due to nano size—best within 15-25 feet of the router Needs driver install on older versions of Windows or macOS (not plug-and-play everywhere)

Limited Life
Edit: While my overall experience with the dongle as reviewed below was a 2 star experience, customer support and assistance was fantastic. For the price and knowing they stand behind their product, it is hard to go wrong with this adapter. This worked okay for a few months. But about 4 months in it totally died. It was relatively stable up to that point, but nothing to brag about which is expected for this price point. I would have liked to get at least a couple years out of it.
