What we like
- Full aluminum case with real gasket-mount feel for under $200
- Hot-swappable 5-pin MX sockets, no soldering
- Double-layer foam dampening produces a clean, low-pitched typing sound
- Doubleshot keycaps and per-key RGB out of the box
Could be better
- Wired-only — the wireless version costs more
- Glorious Core software is functional but less polished than VIA/QMK
- Heavier than plastic 75% boards, not a travel keyboard
Full Review
The GMMK 3 Pro 75% is Glorious finally building the keyboard their original GMMK Pro should have been. The case is solid CNC aluminum with a real gasket-mount system — not the half-measure “gasket-style” foam strips you see on cheaper boards — and the typing experience reflects it. For $170, it’s the closest you’ll get to a custom-built 75% without learning to solder.
Build and Sound
The aluminum case has zero flex and the gasket mount gives a noticeably softer bottom-out than rigid tray-mount boards like the original GMMK Pro. Double-layer foam plus a PE switch pad kills the hollow ping and pingy spring noise that plagues budget aluminum boards. The stock Glorious Fox linears sound deep and creamy out of the box, and stabilizers are pre-lubed well enough that most people won’t bother retuning them.
Modularity and Switches
The 5-pin hot-swap sockets accept basically any MX switch on the market, which is the whole point at this price. Glorious also sells modular plates, weights, and cases if you want to tinker, but the stock configuration is good enough that most buyers won’t touch it. The doubleshot ABS keycaps in Cherry profile are fine — not GMK, but better than the thin keycaps Keychron ships on the V-series.
Software and Daily Use
Glorious Core handles RGB, remapping, and macros. It’s not VIA and it’s not QMK, but it works on both Windows and Mac, and key remapping syncs to onboard memory. The 1000Hz polling is plenty for typing and non-competitive gaming. There’s no wireless on this version — if you need Bluetooth or 2.4GHz, the GMMK 3 Pro Wireless is a separate SKU and costs more.
How It Compares
Against the Keychron Q1 ($200) and Q1 Ultra ($300+), the GMMK 3 Pro splits the difference: better sound profile than the Q1, no wireless or 8K polling like the Q1 Ultra. The NuPhy Halo75 is comparable on price but uses a plastic case and feels noticeably less premium. If you want a wired aluminum 75% that sounds like a $400 custom build, this is the one.
Who Should Buy This
Buy the GMMK 3 Pro 75% if you want a true aluminum gasket-mount keyboard but don’t want to spend $300+ on a Keychron Q1 Ultra or build a Mode Sonnet from parts. Skip it if you need wireless (get the Pro Wireless or a Keychron Q1 Pro instead), or if you prefer the open-source firmware ecosystem of QMK/VIA boards.
