Who it's for
Suits owners of a 1080p television who want Roku's app catalog at a lower cost than a 4K player. Not the right choice for anyone with a 4K set who wants to use its full resolution.

Performance notes
The player streams over Wi-Fi and outputs up to 1080p Full HD, so 4K source content is scaled down to fit the display. At 1.3 pounds it sits close in weight to the other 1080p Roku player in this batch.
