YUNZII QL108

Manufacturer: YUNZII

The YUNZII QL108 is a full-size mechanical keyboard that combines a low-profile design with an aluminum and plastic case, available in black or blue colorways. It features a tray mount construction, adjustable feet, a detachable cable, and is noted as being compatible with Mac layouts, making it a versatile option across different setups.

Under the hood, the QL108 uses Onyx Gray Tactile Switches with an actuation distance of 2.2 mm, an actuation force of 43 g, and a total travel distance of 3.9 mm. The board supports hot-swappable switches, runs at a 1000 Hz polling rate, and includes N-key rollover (NKRO) for full simultaneous keypress registration. Keycaps are double-shot ABS in a DSA profile with a standard ANSI layout, and media functions are accessible via the Fn key.

Pros
  • Hot-swappable switches allow for easy switch replacement without soldering
  • N-key rollover ensures all simultaneous keypresses are accurately registered
  • Full-size 100% layout retains a complete key set including the numpad
  • Detachable cable makes transport and cable replacement more practical
  • Aluminum plate and case construction adds structural rigidity to the build
  • Adjustable feet provide some flexibility in typing angle
Cons
  • Tray mount design offers less sound dampening compared to other mount types
  • No VIA, QMK, or ZMK support limits firmware-level customization options
  • Media controls are only accessible via the Fn key, with no dedicated media keys
  • No wrist rest is included
  • The keyboard weighs 1250 g, which makes it less portable than lighter alternatives
  • South-facing LEDs may result in less even RGB visibility through keycaps
Who is this for?

The YUNZII QL108 is well-suited to users who want a full-size mechanical keyboard with a low-profile form factor for everyday typing or office use. The hot-swappable tactile switches make it a practical choice for those who like to experiment with different switch feels without needing soldering equipment. Users who value a clean, minimal desk setup will appreciate the detachable cable and aluminum-reinforced build, while Mac users benefit from dedicated Mac key compatibility out of the box.

Who is this NOT for?

Users who rely heavily on firmware customization tools such as QMK, ZMK, or VIA will find this keyboard limiting, as none of these are supported. The tray mount construction and lack of advanced features like rapid trigger or adjustable actuation make it less appealing to competitive or enthusiast-level users who require precise input control. Additionally, those who prefer a more ergonomic setup may find the absence of an included wrist rest a drawback for extended sessions.
