Xteink's latest creation, the X4 Pro, is a mini marvel for book lovers. Its sleek design and touchscreen make it an instant classic in the e-reader world.

Despite its diminutive size, the X4 Pro offers some impressive features. It’s not just a cute gadget; with its front light, it turns into a practical nighttime companion for those who like to read before bed. However, the tiny screen might disrupt your sleep routine if you prefer scrolling through social media.

Compared to its predecessors, the X4 Pro is more user-friendly and versatile. Its magnetic pogo charger adds an extra layer of convenience, though it’s a small change that may not appeal to everyone due to USB-C preferences. The updated software brings in new possibilities, but the process of adding content remains somewhat cumbersome.

While the Xteink devices are fantastic for personal reading, they might not be ideal for borrowing e-books from libraries as their compatibility with certain formats is limited. For now, you're better off sticking to .epub files purchased directly from publishers.
