Xteink X3 Live Now

This may be a bit of a rant but here’s my perspective: The product XTEINK are busy selling is a small e-ink screen, not a book reader. The device is really cool because it’s minimalistic and pocketable but in order to be a book reader it lacks: decent epub rendering capability: it improved recently

Lightest e-ink devices

Check out xteink x4, it's 74g. Note that the software is very limited as it runs on the ESP32-C3 MCU. There is also Obook 5 at 100g. No need to ask here, just open https://comparisontabl.es/e-readers/ and sort the table by weight to see them all. Screenshot of the top lightest devices:

Easiest/cheapest?

Seconding the posts suggesting looking at second-hand readers - e-readers have fragile screens but otherwise it’s tech that holds up well, so a second-hand Kindle or Kobo or PocketBook that is in a decent shape (the screen is intact) will be fine for this purpose. Even very old ones (15 years old) s

XTINK S4 Leaks

I haven’t touched my Kobo because I can’t sync to it, and don’t feel like finding the page I’m on. Page number 6,879 doesn’t really equate to anything of meaning for other normal-sized eReaders. I’m reading IT currently, and started reading the physical book, but have read a good 20% on the X3. I ju

Got myself the smallest e-reader so far: the XTeink X4!

  • font size: normal and small * page turning: fast * marking/highlight text: no (no-touch screen, it is a button-operated device) It is very limited in everything. It really is not more than a toy that offers only one thing: reading texts and (most) epubs. I find the screen very nice that makes for very

Found the perfect light for my X4

I mostly read in dark rooms, yes. Like 75%. I read at night, in bed, next to someone. That is where e-readers shine, imo. Light weight/portability and absolutely amazing built in light. That is what really makes the devices great. I mostly read big heavy fantasy books. Reading those on a front-lit e
