DAZN is already available in DACH and Japan - probably worth testing whether a VPN gets around their blocks beforehand. I tried when it first started up in Germany and couldn't get it to work.
Good point. Express has a 30 day money back guarantee and seems to be one of the more reliable ones so will probably go for that and then sack it off if it doesn't work.
Out of curiosity what sort of content were you after from DAZN that they previously had already?
