Score: 81/100
Bigme B7 Pro Blue
Score: 82/100Rankings
The Bigme B7 Pro is a 7-inch color e-ink tablet powered by a high-end Dimensity 1080 processor and 8 GB RAM, offering strong performance and extensive connectivity. Its color resolution is modest and battery life can be short when using 4G. Ideal for users who want a lightweight Android-based e-reader with phone-like features.
The Kobo Libra Colour is a 7-inch waterproof colour e-reader with a Kaleido 3 display, 32 GB storage and support for a magnetic stylus. Its colour and stylus capabilities consume more power and the lack of expandable storage may limit long-term library growth. Best for comic and manga fans or note-takers who want a portable colour device with a larger screen.

Professional reviewers applaud the Libra Colour for its lighter chassis, upgraded 2 GHz CPU and the vibrant Kaleido 3 screen that makes comics and PDFs come alive. They also caution that the color features and optional stylus increase power consumption and that the fixed 32 GB storage cannot be expanded.
Everyday users love the portable 7-inch form factor, the ample 32 GB library capacity and the vivid colors for manga and cover art, while repeatedly noting the strong battery life after prolonged use. Common complaints revolve around the separate stylus purchase, lack of expandable storage and occasional lag when handling high-resolution images.
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.
