Glorious GMMK 3 Pro 100%

Manufacturer: Glorious

The Glorious GMMK 3 Pro 100% is a full-size mechanical keyboard built for gaming use, combining an aluminum and plastic construction with a standard 100% layout. It uses a gasket mount design, which sits beneath the internal plate to shape the overall typing feel, and comes with a detachable cable for easier desk management. The keyboard is available in black and silver colorways and includes adjustable feet for positioning preference.

At the core of this keyboard are Glorious Fox HE Hall effect switches, a linear-feel switch with a 45 g actuation force and 4 mm total travel distance that also supports hot-swapping without soldering. Rapid trigger and full N-key rollover are both supported, while the keycaps are double-shot PBT in an OEM profile with an ANSI layout. A rotary dial is included on the board, with media functions accessible via the Fn key layer. RGB backlighting is present throughout, and the keyboard carries a 2-year warranty.

Pros
  • Hot-swappable Hall effect switches make it easy to replace or change switches without soldering
  • Rapid trigger support adds responsiveness for gaming use cases
  • N-key rollover ensures every simultaneous keypress is registered accurately
  • Gasket mount construction provides a more cushioned typing feel compared to rigid plate mounts
  • Detachable cable simplifies transport and cable management
  • Double-shot PBT keycaps are durable and resistant to shine over time
Cons
  • No support for QMK, ZMK, or VIA firmware, limiting customization options for advanced users
  • Media functions are only accessible via the Fn key, with no dedicated media keys
  • Does not include a wrist rest, which must be sourced separately
  • Wired-only connectivity with no wireless option
  • No USB passthrough port on the keyboard itself
Who is this for?

This keyboard is well-suited for PC gamers who want a full-size layout with responsive Hall effect switches and rapid trigger support for fast-paced gameplay. The hot-swappable switch design makes it a practical choice for users who enjoy experimenting with different switch feels without soldering, while the gasket mount and N-key rollover cater to those who value both typing comfort and input accuracy during extended sessions. The RGB backlighting and rotary dial also make it a reasonable fit for users who want some physical control customization on their desk setup.

Who is this NOT for?

Users looking for wireless connectivity will find this keyboard unsuitable, as it operates exclusively over a wired USB connection with no Bluetooth or RF option available. It is also a poor match for those who rely on open-source firmware such as QMK, ZMK, or VIA for deep key remapping and macro programming, since none of these are supported. Additionally, Mac users or those working in cross-platform environments may find the lack of Mac-specific key support a practical inconvenience.
