I do better with my phone streaming to a Chromecast than either using a smart TV or a Firestick. The Firestick is convenient but it beffers the goes fuzzy. I have to back out of the game and start it again and it will be all right for a while. But I have to do this maybe 5-6 times during a game. The Chromecast does great. ESPN+ never buffers on my phone, iPads or laptop ? only on the TV?s.
