Pros and Cons

What We Liked

  • The Fire TV Cube is incredibly fast, thanks to its octa-core processor. App starts are lightning-fast and it’s 2X as powerful as the Fire TV Stick 4K Max.
  • The hands-free Alexa feature is a game-changer. I can control my compatible TV, soundbar, and receivers with just my voice, even from across the room.
  • It’s seamless to navigate between different entertainment sources. I can easily switch from streaming to my cable box, game console, or even my webcam.
  • The Fire TV Cube supports the latest Wi-Fi 6E technology, ensuring smooth streaming and a reliable connection.
  • The picture quality is outstanding, with true-to-life 4K visuals and support for Dolby Vision, HDR, and Dolby Atmos audio.

What Can Be Improved

  • One drawback is that it’s not as easy to sideload apps on the Fire TV Cube Gen3 compared to its predecessor. I hope Amazon addresses this limitation in future updates.
  • The Alexa App software can be glitchy when used with the Fire TV Cube, especially when you have multiple Fire TV devices in your home. It requires some trial and error to get everything working smoothly.
