What reviewers say
Reviewers agree the small screen is sharp and easy to read, the battery lasts for weeks, and the magnet makes it easy to carry on the back of a phone. Both found the stock software clunky and switched to the open-source CrossPoint firmware, and both disliked the separate pogo-pin charging cable; Six Colors also found the magnet weak, and both note it can't read DRM-protected shop or library books.
