Good in every way...
I'm very happy with it: it's elegant, functional and complete (5G and WiFi 6, in 2.4 and 5 GHz, what more could you ask for?).
Its interface (the small screen is touch-sensitive) is simple and functional, but for more advanced configurations (such as changing the SSID and WiFi keys) you have to use the web administration interface, as with all routers. There aren't many options, but everything you need is there.
The only downside is that you have to search for the user manual on the web, which isn't easy. It's also bigger than the photos suggest; you *can* slip it into your pocket, but it's better to have big pockets...
I'm using it with Orange's (free!) 'MultiSIM' option, which it recognised straight away. No more tying up my phone to provide internet to all these people on the move, now tablets and laptops can have internet just about anywhere.
Oh yes, and after unpacking and installing the SIM, don't forget to give it an update (or two). It took me two before it was finally up to date.
