We like it quite a bit. We also have Acorn (another Brit streaming service), and we think BB has programming that’s more suited to us, and I think a larger library, plus a larger “live” broadcast. They showed the coronation in real time, for example.
Acorn is good as well, and they have a fair amount of Australian programming as well. I’m not sure if that’s available to you (I don’t think so), but we seem to watch more on BB.
I don’t think they have a referral reward, thanks though. Also, you can order it through other streamers, like Amazon Prime and Apple. We originally ordered it through Apple, but it was such a pain managing the account that we cancelled it after a couple of months and signed up again direct with BB.
I think they also offer a free week trialing period.
