As I say, impressed, and to be honest even at £89/month inc VAT this is good value...
A doddle to install properly, some tree cover is unavoidable, but it works, and is happily doing 185Mb/s right now. Thanks to Jim to coming round with his drill for me.
The IPv4 is all CGNAT, and the IPv6 is not working yet or reliably. But this "just works" with A&A L2TP providing fixed IPv4 and IPv6 over it. And the latency makes this a very viable service at around 30ms. The package of a Starlink + FireBrick + A&A L2TP is pretty appealing, to be honest.
I really am pretty gobsmacked with how simple this all was to buy and get working - only caveat is "remember to get the Ethernet adaptor".
