SUPERNOTE A5 X vs REINKSTONE R1: Which e-ink tablet is best?

This page was created to explore the similarities and differences between two e-ink tablets; the RATTA SUPERNOTE A5 X, and the REINKSTONE R1.

This is currently a simplified comparison consisting of a table of side-by-side specifications, and review cards of each tablet, outlining their pros and cons. If a tablet has a rating then you can also click on it for a full and detailed review of the tablet.

I do write detailed ‘versus‘ comparisons, however because I am only one person it is impractical for me to compare every single e-ink tablet against every other one! So if you think that this page would benefit from being fleshed out with additional information and my own thoughts and opinions, then feel free to drop me an email at dan@ewritable.com – I will prioritise pages that get the most requests 🙂

I have also created a gigantic e-ink comparison table (which is also searchable/filterable, so you can whittle down your search to the tablets that best meet your needs).

And a list of (what I believe to be) the best e-ink tablets can be found here.

Now, onto the comparison between the RATTA SUPERNOTE A5 X and the REINKSTONE R1.

RATTA SUPERNOTE A5 X Review Card

Overall rating

Pros

  • Fantastic substitute for a paper notebook
  • Ceramic stylus tips that never need replacing
  • Lovely writing feel
  • Quick and easy navigation
  • Well-structured notebooks
  • Best handwriting search
  • Excellent after-sales service
  • Nice range of additional tools (Email / Calendar / Word Doc editor / Kindle etc.)

Cons

  • Steeper learning curve
  • Notebooks not easily viewable on other devices when using third-party clouds
  • Partner app requires more work
  • No frontlight
  • No auto-synchronisation

The Supernote A5 X (and smaller A6 X) are perhaps the best digital replacements for paper-based notebooks for those that love to write.

REINKSTONE R1 Review Card

Overall rating

Pros

  • More colours

Cons

  • Limited availability
  • Shipping delays
  • Inconsistent communication
  • Screen 'staining'
  • Ghosting
  • Poor performance

NOT RECOMMENDED: This was a Kickstarter campaign, and the backers have reported long shipping delays, inconsistent communication and a poor quality product when it was finally delivered. Therefore, this tablet is not recommended and all ratings have been set to zero.

Dan Dutton is passionate about E-ink writing tablets, which bring together the pleasure of writing on paper with the power of digital technology. When he bought his first tablet, he realised that there wasn't a lot of unbiased information available for people that were considering buying an E-ink tablet, and so he built eWritable.
