Overview
Not a smart TV or a game console, this compact streaming player adds apps to any screen over HDMI. A voice remote handles search and controls the TV's power and volume, and the wireless radio carries the stream.
Setup is quick, since the HDMI cable comes in the box and the remote controls the TV. Apps from major streaming and live TV services are supported. The listing does not state a power adapter or remote batteries.
Who it's for
A household adding streaming to a TV that lacks apps or whose built-in system feels slow. Buyers who need Ethernet or disc support should look elsewhere.
Pros and cons
- Voice remote controls TV power
- HDMI cable included
- Supports high dynamic range
- Works with Alexa and Google Assistant
- Power adapter not listed
- Wireless only for networking
- Connects over HDMI only
Performance notes
The player decodes streams and sends them over HDMI, so picture quality depends on the TV and the stream's resolution. Video travels over the home network, which means router distance and interference affect buffering. The remote's infrared control handles the TV power and volume without extra setup.
