Glorious GMMK 3 Pro 75%

Manufacturer: Glorious

The Glorious GMMK 3 Pro 75% is a compact mechanical gaming keyboard built around a gasket mount construction that sits within a mixed plastic and aluminum chassis. Available in black and silver, it offers a 75% form factor with a standard ANSI layout, adjustable feet, and a detachable USB cable, making it a structured option for users who want a smaller footprint without sacrificing a dedicated function row.

Under the hood, the GMMK 3 Pro 75% uses Glorious Fox HE Hall effect switches with a linear feel, 45 g actuation force, and 4 mm of total travel distance — and the switches are hot-swappable. The board runs at a 1000 Hz polling rate, supports full N-key rollover, and includes rapid trigger functionality. Keycaps are double-shot PBT in an OEM profile, and a rotary dial is included for on-the-fly input control. Media functions are accessible via the Fn key layer.

Pros
  • Hall effect switches are hot-swappable, making it straightforward to replace them without soldering
  • Rapid trigger support adds responsiveness for precise keypress registration
  • Full N-key rollover ensures every simultaneous keystroke is reliably registered
  • The gasket mount construction provides a softer, more cushioned typing feel compared to rigid plate mounts
  • Double-shot PBT keycaps are durable and resistant to shine over time
  • A rotary dial is included for convenient on-the-fly control adjustments
  • The detachable USB cable simplifies cable replacement and transport
Cons
  • No QMK, ZMK, or VIA support limits customization options for users who rely on open-source firmware
  • Media functions are only accessible via the Fn key layer, with no dedicated media keys
  • No wrist rest is included in the package
  • The keyboard is not designed with Mac-specific keys, which may inconvenience macOS users
  • Adjustable actuation and dual actuation are both absent, reducing switch behavior flexibility
Who is this for?

This keyboard is well-suited for PC gamers who want a compact 75% form factor without sacrificing a function row, particularly those who value the responsiveness that comes with Hall effect switches and rapid trigger support. The hot-swappable switches and gasket mount construction also make it a solid fit for users who like to tune their typing experience over time without committing to a fixed setup. The inclusion of a rotary dial and full N-key rollover further appeal to those who want practical input controls during fast-paced sessions.

Who is this NOT for?

Users who rely on open-source firmware ecosystems like QMK or VIA will find this keyboard limiting, as none of those platforms are supported. It is also a poor match for macOS-focused users, since the layout is not designed with Mac-specific keys in mind. Additionally, those who prefer extensive software-driven switch customization — such as adjustable actuation points or dual actuation modes — will find the feature set insufficient for those needs.
