Overview
A 3.7 inch E Ink reader weighing about 58 grams and 5.1mm thin, built to slip into a pocket rather than a bag, with gyroscope page turning, physical buttons, and 16GB of storage expandable to 256GB.
This is a small-screen, single-purpose reading device rather than a tablet substitute, closer to a keychain-sized companion for books, manga and notes than a full library reader. The magnetic pogo-pin charging and included adhesive ring let it stick to a compatible phone case, and the high-aluminosilicate glass front is the tradeoff for its slim body: it reads well but wants gentle handling.
- 3.7 inch E Ink display, 5.1mm thin
- 16GB storage, expandable to 256GB
- Adhesive metal ring for magnetic mounting
- Up to a week of casual reading per charge
Who it's for
Readers who want something pocketable for commutes and quick breaks without a phone's notifications pulling focus. Not a fit for anyone wanting a large display, stylus notes, or a device to survive being dropped in a bag with keys.
Pros and cons
- Pocket sized at about 58 grams
- Gyroscope tilt plus physical button page turns
- Expandable storage up to 256GB via card
- Magnetic pogo-pin charging port
- Small 3.7 inch screen limits reading area
- Glass display needs careful, gentle handling
- Modest battery life at about 10 hours
Performance notes
Page turns come from either a gyroscope tilt gesture or the physical buttons, aimed at one-handed reading while standing or commuting. Battery is rated up to 10 hours of reading, roughly a week of casual use per charge, refilled through a magnetic pogo-pin connector rather than a port. The glass front is high-aluminosilicate, which the listing flags as needing care around impacts, pressure and bending.
