I don't think they necessarily compete for the same market as some of these other routers. This seems way more compact than many of the other options on the market. I just briefly looked around on Amazon and even many other wifi 5 routers look to be about 2x or thicker than this one. Compared to the GL.inet Opal for example, it's about 20mm smaller in each dimension: 118 x 85 x 30mm (Opal) vs. 95.95 x 65 x 12.5 mm (Unifi). The Unifi is pretty close to a tiny 5000 mAh portable battery.

Now what I'd be really more interested in a Pro version, more so than wifi 6, would be a built-in modem with SIM/eSIM.
