What reviewers say
Reviewers agree the front light and touchscreen make it far easier to use than earlier Xteink readers, good enough for reading in bed, and that the battery lasts for weeks. The magnetic pogo-pin charging in place of USB-C is the common complaint; Android Police also found the software short on fonts and the button layout unintuitive, and TechCrunch found the dimmest light setting slightly too bright.
