Not a huge fan of the size of the screen, but it seems nice otherwise. I actually appreciate it being a little thicker because I have big hands and gripping thin things hurts after awhile.

No buttons, no DRM, no notifications, no algorithm deciding what I should read next. Somehow an ESP32 powered e reader feels more rebellious in 2026 than most flagship gadgets. I just hope the touchscreen is good enough that turning a page does not become a mindfulness exercise.

The specs on this are terrible. I wouldn't buy it for $29.
