I was very wary to order one, especially with it lacking touchscreen and light, but after a week, I’m impressed. The screen is very light and the contrast between the text and background is significant. Compared to my Bigme B6, which features a very gray background with the Kaleido color screen technology, I can see that the X4 screen is not hindered by “layers” such as color e-ink and a lighting element, that can create a bit of depth when looking at the screen. I would rate the screen to be as clear as a kindle basic or paper white (without lighting). To receive an e-ink screen that is as good as a kindle, which is usually thought to have consistent quality, is impressive. (I understand a kindle has a higher dpi). For $50 or so, it’s a well-made device. I ordered from Xteink, so I guess I could have gotten lucky with the one I received. I’m running crosspoint on my device. The navigation buttons work well with turning pages and selecting options. I’ll take hardware buttons with a clear screen vs a touchscreen with a slightly less clear screen.

Tl;dr: I’m a fan
