YUNZII B87 Wireless Mechanical Keyboard TKL - Programmable, Gasket

In this review the YUNZII B87 is evaluated as a compact TKL mechanical keyboard that aims to balance typing comfort, customization and desk-friendly aesthetics. The biggest reason to consider it is the combination of QMK/VIA programmability and tri-mode connectivity, which makes it a versatile choice for users who switch between devices or want deep layout and lighting customization. Physically it stands out with cute dye-sub PBT keycaps and an included wrist rest that together create an attractive and comfortable setup for daily work and gaming.

Key Features

• Tri-mode connectivity: Bluetooth, 2.4 GHz and USB-C wired modes let users switch between up to five devices for flexible multi-device workflows.
• QMK/VIA programmable: Open-source customization via QMK/VIA enables remapping, macros and custom backlight effects from a web browser on Windows or Mac.
• Gasket mount design: The gasket structure plus five layers of sound-absorbing filling and pre-lubed linear switches reduce resonance for a softer, cushioned typing feel.
• Hot-swap sockets: Full-key hot-swap support for 3-pin and 5-pin switches makes changing switch types easy without soldering.
• Long battery life: Built-in 4000 mAh battery supports extended wireless use so you do not need to charge frequently during normal daily use.
• Comfort accessories: The included ergonomic wrist rest is made from skin-friendly ABS and adds stability and comfort for longer sessions.

Who It's For

The B87 is best for keyboard enthusiasts and multitaskers who want a programmable TKL with strong customization and reliable multi-device wireless options. Gamers who prefer a compact 87-key layout and those who like tinkering with switches will appreciate the gasket mount feel and hot-swap sockets.

It is less suitable for users who need a numeric keypad or who expect flawless out-of-the-box connectivity in every environment; a few customers reported mixed Bluetooth performance, so anyone whose primary workflow depends on rock-solid Bluetooth in challenging RF spaces may want to test before committing.
