Doesn't always work. I'm not in the US. So shows that it says are on a service, aren't in my country, or if it's on a service, it doesn't know because it's on that service in my country and not the us. For me, Justwatch.com, has been more miss than hit. Sometimes, asking google works, but some services that are available in my country won't integrate with Google in my country, but if use a VPN for the us on my Android TV it loads all the US features and the integration starts working and everything is correct. So yeah, unless you're in the US, the experience of figuring out where it is what you want to watch is more miss than hit.
