Geonix Rev.2.5
Finding the perfect balance between sharpness and softness.
From sharpness to softness: GEONIX Rev.2 — an evolution and balance in keyboard design. With the arrival of GEONIX Rev.2.5, the design language proven by time continues, refining every detail without changing its essence. Stability, sound, tactile feel, and interaction have all been recalibrated; the classic is preserved while the details continue to evolve.
Because truly lasting design is never about starting over—it is about continuously moving closer to perfection through restraint.

Design
Semi-Aluminum & Full-Aluminum
Luminum Construction – CNC-milled from premium aluminum for durability and a solid, weighty feel. The semi-aluminum design emphasizes light transmission, allowing the RGB lighting to shine vividly through the sides for a more immersive visual effect.


Stability
![]()
Dual1U&2U
Based on feedback from previous Rev.2 users, we conducted multiple rounds of optimization testing, further improved the 2U stabilizer solution, and introduced a Dual 1U version—offering more choices and greater flexibility for users.



Boat-style case
The boat-style chassis creates a smoother and more sculpted side profile, giving the keyboard a lighter visual presence while enhancing the premium feel of the aluminum body.
Combined with a five-layer acoustic package for an improved typing feel and enhanced anti-static protection for safer everyday use, Rev.2.5 delivers a more refined and reliable experience overall.


Independent daughterboard design
Safer, more reliable, and more stable.

Keycaps
LCK & LAK Keycaps
LCK keycaps are made from transparent PC material with UV-printed legends, delivering excellent light transmission for bright and vivid RGB effects.
LAK keycaps are crafted using PBT with dye-sublimation legends, offering a more durable, long-lasting finish that resists wear over time.
Both options are built for everyday use with a premium feel—one focused on vibrant lighting, the other on lasting durability.
Which one would you choose?


Support VIAL and Tri-mode connectivity
Plug and play, with more powerful programmability.

Switches
Rev.2.5 offers 5 different Kailh Choc V2 switch options, covering both linear and tactile styles.
You can choose freely based on your typing preference—whether you prefer a smooth, uninterrupted linear feel, or a more responsive tactile feedback.
Whether you're looking for quiet smoothness or clear keypress confirmation, there’s now a switch that better fits your style.



System Mode Switching
Q: How do I switch to Windows mode?
A: Press Fn + U. When the keyboard indicator light flashes, it means the keyboard has successfully switched to Windows mode.
Q: How do I switch to Mac mode?
A: Press Fn + Y. When the keyboard indicator light flashes, it means the keyboard has successfully switched to Mac mode.

Tips:
The default keycaps for all-aluminum models are LAK, while for semi-aluminum models, they are LCK. If you need to change the keycaps, please contact the customer service for modification.
I have more than 10 Planck style keyboards, a mixture of official boards and custom designs, this is my first wireless one though. It works really well with my custom layout using QMK and the build quality is solid. Switches feel and sound nice. I really like it. Price is good too.
As a Colemak user maybe some more variety in supplied keycaps would be welcome. Just offering lak black blanks would be good for me.
Well recommended.

Title: The Ultimate Minimalist Unibody Keyboard
The quality of the case is outstanding. At this price point, it feels revolutionary. I purchased the full-aluminum version, and it has a truly premium feel.
The choice of switches greatly affects the typing experience. I chose the silent linear switches, and the gasket mount also works very well.
Above all, it is simple while still offering a sensible number of keys. It also has an undeniable charm.
As for the drawback, I normally use a split keyboard. Because of this, I clearly notice that a unibody keyboard does not allow my shoulders to remain as open as a split keyboard does.
The “Hold on other key press” and “Permissive hold” options on the Vial are not working (at August 2026).
I would like to request a firmware update.
This keyboard is incredibly sturdy and solid.
I've ordered also a set of clear keycaps that are very good in quality.
I'm not giving 5 stars because the screws on the plate are hitting the keycaps creating a different noise for some of them.
In brief this keyboard is almost perfect
