Overview
Roku lists this TV stick with an HDMI connector, Wi-Fi and Bluetooth, and a long line of smart home links. Remote and voice control are listed as controller types.
Broad smart home support and a small stick form are the reasons to look at it. The limitation is that the picture tops out at the listed resolution and the contents name only the stick.
Who it's for
A smaller TV with an HDMI input and a Wi-Fi network is the setup this stick addresses. Owners of 4K sets, or shoppers who must be sure a remote is included, should look at higher resolution players.
Pros and cons
- Small stick form
- Smart home support listed
- AV1 codec listed
- Five services named
- Remote not named in contents
- No Ethernet listed
Performance notes
Picture quality is capped by the listed resolution, so a 4K TV will upscale the picture. Wi-Fi quality governs how smoothly streams play. Codec support, including AV1, decides which streams reach the TV in their native form.
