I got an Xteink X4 a month ago. It's perfect: none of the distractions of a phone, battery life measured in weeks, small enough to carry everywhere, cheap enough that I don't worry about anything happening to it.
So far I have only read one book on it. But that is Tolstoy's "War and Peace" (361 chapters, 1300 pages in paper editions), which I'd never managed to read more than a few tens of pages of before.
Which is pretty solid proof of how nice the X4 is.
I just got the X3 and i love it for all those reasons. I have a card holder wallet that it fits right onto so I have it everywhere. I am reading so much more instead of checking my phone to fill random down time. I wondered if the small size would be annoying to read on, but since page turns are so quick and easy, I have zero issues. I'm actually starting to prefer it to my Kindle for longer reading because it is so light, I can hold it longer or in more random reading positions without any hand fatigue (as minor as that is with a Kindle).
By the way, I'm in the UK. I bought it on eBay UK from a guy named "Reliable Trove" who imports them and reflashes them with CrossPoint.
I know it's not hard to do, but I needed it to work first time before my summer holiday, couldn't wait for a Chinese import, and had no spare time to mess around with putting new firmware on it.
Just FYI for anyone reading this. "Easy to do" is an understatement. It's merely a matter of connecting the reader to the PC with a USB cable and then click the button on the webpage. The whole process is automated and done over the web.
I use it for my daily commute, spending my ride reading instead of doomscrolling. I just finished “A Confederacy of Dunces” and now I’m on “Lonesome Dove”.
I didn’t imagine how much I’d use a tiny, pocketable reader. I love it.
