The Roku Streaming Stick 4K arrived with a heavy task on its shoulders: replace the best streaming device. Yes, this $50 stick is the follow-up to the Roku Streaming Stick Plus, and while it's not a huge leap over that model, it fixes one of the biggest flaws of that model and keeps everything we loved about it while doing so.
And while that sounds like it might be a minor update, the major new feature added is Dolby Vision, which could be enough to make some upgrade today. Roku's also claiming faster performance, which is a trickier thing to measure on a streaming device. That said, this Roku Streaming Stick 4K review will show why it's a worthy successor to the throne, and sitting at the top of the best Roku devices list too.
