Pros

•Includes 4 tuners, offering a significant advantage for simultaneous recording or viewing.
•Functions exceptionally well and meets user expectations for streaming and DVR use.
•Initially easy to set up and worked across multiple platforms like iOS, Windows, Plex, and Firestick.
•Works great with Roku under perfect reception conditions.
•Compatible with the Channels app, which is efficient on older computers.

Cons

•4K ATSC 3 capability is largely ineffective due to encryption of most channels.
•Poor compatibility with Plex and Roku devices; units malfunction or have interface issues.
•Significant customer support shortcomings, including unresponsiveness and unclear return procedures.
•Additional costs, including a $35/year fee for guide updates and DVR, and necessary additional hardware like NAS.
•Audio issues and signal freezing, requiring manual reloading when the connection is lost.
•Licensing fees under ATSC 3.0 may be significant, and there's a lack of support for DRncrypted channels.
•Cannot be used with cable services like Xfinity, only with a local TV antenna.
•Frustrating app interface and scheduling layout hinder usability.

Bottom Line

The SiliconDust HDHomeRun Flex 4K ATSC 3.0 NextGen TV offers decent functionality with the benefit of four tuners, but its usefulness is hampered by limited channel encryption, poor compatibility with common streaming devices, and cumbersome customer support. If you're looking for a more user-friendly ecosystem, consider alternatives like the Tablo, which offers comparable functions without a recurring subscription fee.
