Summary of "Ultimate Boox Go 7 Review: Black, White and Color Gen II, Compared Using the New D.A.F. Methodology"
Ultimate Boox Go 7 Review Summary
Product Overview
The review covers three Boox Go 7 devices:
- Go 7 Black
- Go 7 White
- Go 7 Color Gen 2
All three share the same internal hardware (SoC, 4GB RAM, 64GB storage, expandable via microSD), run Android OS with Google Play support, and offer similar general functionality. The primary differences lie in their screen technology and related user experience aspects.
Main Features & Differences
Boox Go 7 Black
- Glass screen cover with anti-glare (AG) glass surface.
- Heavier weight at 195g compared to the white version.
- Lower reflectivity intensity but better diffusion of reflections, resulting in less sharp reflections.
- Buttons protrude more but do not stick.
- Screen offers better contrast and slightly better overall readability than the white version.
- Front light max intensity around 532 lux, well-calibrated but lower than white version.
- Writing latency approximately 50 ms (lowest among the three).
- Surface roughness higher than white and color versions, with sharper peaks due to glass surface.
- Battery life:
- ~50 hours reading (front light off)
- ~33 hours reading (front light 50%)
- ~10 hours reading (front light 100%)
- Good ghosting performance, especially in HD and A2 refresh modes.
- Highest DAFF display analysis score overall (46.46).
Boox Go 7 White
- Plastic screen cover (PMMA), lighter at 186g.
- Reflectivity intensity similar to black but with sharper, more defined reflections (worse for glare).
- Buttons sometimes stick due to snug fit of plastic cover around buttons (major usability issue).
- Screen is crisper and sharper than black version but with worse reflectivity.
- Front light max intensity very high at 839 lux (unusually bright).
- Writing latency about 59 ms.
- Surface roughness slightly less than black version, with a roughness profile more similar to paper (rounded valleys).
- Battery life similar to black version.
- Slightly worse ghosting performance than black.
- DAFF display analysis score slightly behind black version (43.83).
- Preferred by reviewer for writing feel due to plastic surface’s slight give and different texture, though still unpleasant overall.
Boox Go 7 Color Gen 2
- Color Kaleido (CFA filter) E Ink panel with glass cover.
- Lowest front light intensity among the three.
- Screen is darker, fuzzier, and has significantly less contrast due to CFA filter and color technology.
- Poor color accuracy compared to traditional IPS displays (score 44.1 vs iPad’s 90.3).
- Visually better ghosting performance but masked by CFA filter and lower contrast.
- Highest writing latency at approximately 62 ms.
- Smoothest surface roughness but more slippery due to glass.
- Shortest battery life (~7.7 hours reading at full front light).
- Lowest DAFF overall display score (41.19).
- Not recommended for reading or writing due to poor image quality and contrast.
- Front light calibration is odd; despite needing front light more, it has the weakest front light.
User Experience
- Writing experience on all devices is subpar due to:
- Active digitizer pen with plastic nib.
- High latency (50-60 ms) compared to modern EMR pens (~17-18 ms).
- Low precision and poor pressure sensitivity.
- Glass surfaces feel slippery and “tappy,” plastic surface slightly better but still not enjoyable.
- Boox platform software is powerful, featuring:
- Custom templates
- Audio recording
- Link insertion
- Shape drawing
- Google Play access for additional apps
- Good e-reader functionality with flexible layouts and accelerometer for auto-rotation
- Battery life is decent but drops significantly with front light on high.
- Devices tend to get warm (up to ~44-45°C) during intensive tasks like writing or browsing.
- Magnetic covers provided do not hold the devices securely; covers often fail to hold the device properly, causing it to fall out.

- Excellent e-reader capabilities with powerful Android and Google Play support.
- Versatile platform supporting many file types, custom templates, and multimedia.
- Strong performance in readability and contrast on monochrome versions.
- Good ghosting control, especially in HD and A2 refresh modes.
- Solid battery life for e-ink devices.
- White version offers slightly better writing feel than glass versions.
- Color Gen 2 offers color display, a rarity in e-ink tablets.
Cons
- Poor writing experience on all devices due to pen latency, precision, and surface feel.
- White version has a serious button sticking issue.
- Color Gen 2 has poor image quality, contrast, and color accuracy.
- Front light calibration inconsistent and less refined than Kindle or Kobo.
- Magnetic covers do not securely hold devices.
- Devices warm up noticeably under load.
- Color Gen 2 front light weakest despite needing it most.
- Overall refinement and polish less than competitors (Kindle, Kobo).
Speaker’s Personal Views
- Wanted to like the white version best but was put off by button issues and reflectivity.
- Prefers black version for e-reader use despite heavier weight and black frame.
- Does not recommend any of the devices for serious note-taking or writing.
- Finds Color Gen 2’s color quality not worth the trade-offs.
- Appreciates the Boox platform’s versatility but feels the devices lack refinement.
- Sticks with Kobo Sage for writing due to better experience.
- Recommends these devices mainly for users who want an all-in-one Android e-reader with flexibility and are willing to accept compromises.
- Advises caution on buying white version due to button issues.
Overall Verdict
The Boox Go 7 series offers a versatile and powerful Android e-reader platform with excellent reading capabilities, especially in the monochrome black and white versions. However, the writing experience is disappointing across all models due to pen latency and surface feel, making them unsuitable as dedicated note-taking devices.
- The white version offers a slightly better writing surface but suffers from problematic sticky buttons.
- The black version provides a more refined reading experience overall.
- The Color Gen 2 model introduces color but at a significant cost to contrast, clarity, and battery life, and is generally not recommended unless color display is a must-have.
If you prioritize e-reading and Android versatility over writing performance and device polish, the Boox Go 7 Black or White can be strong contenders. Avoid the white version unless you confirm no button issues, and be cautious about the Color Gen 2’s compromised display quality.
