I have not tried it but they are only available in certain metropolitan areas. Strange marketing plan for YouTube. Vivalive plan is global. If you have internet you can get VIVALiveTV'. There is a lot of competition out there but Vivalivetv offers more channels. Approximately 1000. I believe YouTube has 39. The local networks and 35 cable channels.
YouTube TV has only 20 channels in five major cities only and no movies. All that for $35. Vivalive has way a lot of Channels plus international channels and movies coming soon. So yeah, YouTube TV can't beat that.
