Our first Starlink, bought from Costco in the UK was faulty out of the box. Called the US helpline. New one was delivered the next day if I recall. Customer service is brilliant.
We have Starlink. Hassle free by and large and the support service is excellent if you need to talk to them (we had an initial hardware failure when we first got it).
In terms of certification then getting an EICR done on the whole install is the way forward in order to verify what's there now.
Electrical Installation Condition Report. What was the "PIR", Periodic Inspection Report.
Illbrück FM330 skins up like rubber and really tough rubber at that. It's actually quite noticeable when you cut it compared to even Soudal products which were my previous goto.
