My TV came with ROKU it works fine. I constantly get emails from roku Advertising other products but the emails never explain what these products do or why I might want them. Has anybody with a roku TV found other roku products helpful or useful in some way?
The only product that Roku themselves offer for a Roku TV is the wireless speakers. Anything other than that isn't coming from Roku themselves. You could also connect one of the soundbars, but that's rather overkill since the TV has Roku built in, so you don't need an external player.
