Overview
A cord cutter who wants live TV, music and streaming in one place gets a compact player here. It connects to the TV over HDMI, reaches the network by Wi-Fi and lists USB and AirPlay as well.
Strong wireless reach and a broad named app list are the reasons to look at it, and the stick form takes little room behind a TV. The limitation is the missing remote description, since only TV controls and voice are mentioned.
Who it's for
A TV in a room with a weaker wireless signal gets help from the extended range. A household that wants a wired network, or that needs a detailed accessory list, should look at a box style player.
Pros and cons
- HDR support listed
- Long range Wi-Fi
- Very long app list
- No Ethernet listed
- Remote not described
- Memory and storage not listed
Performance notes
Picture quality depends on the TV, since the stick outputs up to the listed resolution with HDR. Extended range helps a distant router but cannot beat a weak connection. The wide app list decides whether a service you already pay for is available.
