A:Answer I bought mine October 29th because hbo max isn't on roku yet and it streams hbo max perfectly from my phone to my tv without a glitch. Just hook it to your TVs hdmi port, plug it in to a wall outlet, turn on WiFi on your phone or tablet, download the Google home app on your phone or tablet, open Google home and search for devices, connect to Chromecast and let it update then your ready to cast. It's easy to use and works like a charm. You can cast anything from your phone or tablet to your tv without a problem
