Glorious GMBK 75% Review: Genius Innovation or Membrane Mess?

Glorious GMBK 75% Keyboard perspective view
The Glorious GMBK 75% attempts to bridge the gap between membrane affordability and mechanical aesthetics.
  • Unique MX-style cross stems allow for full mechanical keycap compatibility on a membrane board.
  • Aggressive $59.99 price point targets the entry-level market, though it faces stiff competition from budget mechanicals.
  • Features a robust IP57 rating for water and dust resistance, a rarity at this price.
  • Typing experience is described as heavy and potentially fatiguing compared to modern mechanical switches.
  • Includes premium touches like a tactile volume knob and 10-zone RGB lighting.

The Membrane Reimagined: Design and Build Quality

The Glorious GMBK 75% enters a market typically defined by generic office decks and attempts something bold: legitimizing the membrane switch. By adopting a compact 75% layout, Glorious preserves the essential function row and navigation cluster while carving out more room for mouse movement—a critical metric for low-DPI gaming. While the chassis is plastic, its wedge-shaped design offers a surprising amount of structural rigidity with minimal creaking. The inclusion of a dedicated, tactile rotary dial that is fully interchangeable with GMMK 3 accessories signals a level of modularity that is frankly unheard of in the sub-$60 category.

The Typing Experience: Heavy Domes and MX Stems

Typing on the GMBK 75% is a departure from the mushy standard. Glorious has tuned these rubber domes to provide a more tactile ‘clack,’ though the trade-off is a heavy actuation force that can feel somewhat sticky compared to a linear mechanical switch. For the competitive player, this increased resistance might lead to fatigue during marathon sessions. However, the real technical achievement here is the MX-style cross stems. By decoupling the keycap mount from the switch type, Glorious allows users to ditch the default, shine-prone ABS caps for high-end PBT sets, effectively letting a membrane board wear a mechanical ‘outfit’ for the first time without the mechanical price tag.

Final Verdict

7.5/10

The Glorious GMBK 75% is a fascinating experiment in democratizing keyboard aesthetics. While it can’t truly replicate the crisp, low-latency response of a dedicated mechanical switch, its ability to wear any mechanical ‘outfit’ and survive a spill makes it a strong contender for casual gamers on a strict budget. It is easily the best-looking membrane board on the market today, even if your fingers might feel the weight of those heavy domes after a few hours of play.
