What reviewers say

Reviewers agree it is tiny, light and cheap, with good physical page-turn buttons, and that the open-source CrossPoint firmware fixes much of what is wrong with it. The common complaints are the bare-bones stock software, which formats EPUBs badly, and the lack of a touchscreen and front light; Digital Trends also found the unlabelled buttons confusing at first but praised the battery life.
