I've not because they don't have license to show (most? all? any?) of the live rugby I'd want to watch in the UK - so worth checking what they have license to show where you live.
I know there's VPNs I could use but I honestly can't be arsed with all of that.
It's a shame because I'd pay in an instant if I could stream all Prem games legally/high quality/good connection etc.
