Overview
A removable adhesive strip anchors this small Roku player behind or beside a television while an HDMI connection carries the picture, and a voice remote handles search and control.
Roku packs the player, remote, batteries and power adapter together, and the app control gives phone users a second way to steer it. The service list covers the major names, though the listing has odd entries for certification and a spelling error in compatible devices.
Who it's for
Households with a 4K screen and Wi-Fi who want a ready-to-use kit with voice search suit this player. Anyone needing a wired network connection should look at a higher model.
Pros and cons
- Voice remote and batteries included
- App control from a phone
- Smart home compatible
- Adhesive strip for tidy placement
- Certification entry is garbled
- Ethernet not listed
- HDR format not named
Performance notes
Picture quality depends on the Wi-Fi link, the app and the television input. A 4K HDR stream needs a fast connection and a display that supports the format. HEVC is not listed, so the codec entry covers only the older format.
