  1. Oliver Bennett

    Vivid unit is amazing! I have been searching for such a device for years, and it ticks all the boxes. The hardware quality is high and the software is intuitive, open source too!

  2. Benjamin Murphy

    Very well designed product. I have an ongoing smart home project and this little device is a perfect fit.

  3. Lila Reynolds

    This little adorable hardware is totally beyond my expectation: it has everything, no extension board is needed! Its native NVME interface is really a big plus.

  4. Dexter Rivera

    A fantastic SBC with screen, eMMC, PoE, M.2 connector all in one! It is worth every penny.

  5. johnathon

    Really beyond my expectations, love it!

  6. tampaflorida083

    I like the vivid unit computer, though one might think that the cpu is too old I could even play drm material (netflix, disney+, paramount+) using widevine on it.
    A great device, for smart home , too, of course, as it has an onboard display one can use as a command center, for example.

  7. tampaflorida083

    my rating, I forgot it… is five stars

  8. Ethan999

    As an RK3399 with top configuration (4G RAM and eMMC), it performs much better than my Raspberry Pi 4B when playing 4K videos on YouTube. Built-in speaker is convenient too: the unit is always ready to play something, no need to connect external screen and headset etc.

    Adorable machine that plays spotify all day for me!
