Top complaints

Amazon Fire TV Cube (3rd Gen)

Roku Ultra (2024)

  • Expensive for what it adds

    Tom's Guide and PCMag list the price as a con. CNET says a speed bump, faster Wi-Fi and Bluetooth aren't enough for a flagship, and the new remote can be added to any Roku for $30. Roku raised its list price to $150 in July 2026.

  • Crashes and dropped connections for some

    Amazon's review summary says connectivity is mixed, with some owners reporting frequent disconnections, and that some say the device crashes or freezes weekly and the remote doesn't work properly.

  • Remote lost the headphone jack; voice lags

    PCMag and CNET note the new Voice Remote Pro drops the 3.5mm headphone jack. CNET found it slower to respond to 'Hey Roku' than the old remote, and PCMag calls Roku's voice features stiff.
