Professional reviewers commend the InkPad Color 3 for bringing color e-reading into the mainstream with its vivid Kaleido 3 screen, eye-friendly SMARTlight and robust waterproof build, while noting its lack of external storage and heavier chassis.
Everyday users praise the device's portability, long battery life, clear color display for comics and manga, and the convenience of built-in audio, but complain about its relatively heavy chassis and inability to expand storage.
Professional reviewers praise the B7 Pro for its ultra‑lightweight build, crisp black‑and‑white text and the convenience of a full Android OS on an e‑ink device, noting that it delivers smooth performance for reading and basic productivity. However, they caution that the limited color resolution, small screen size and inherent e‑ink latency make it less suitable for visual‑heavy content, positioning it primarily as a text‑focused, portable e‑reader with phone capabilities.
