- •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.

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.
