Glorious Model O2 Mini mouse

The Model O2 Mini Ultra Light Ambidextrous RGB gaming mouse uses a perforated design on the top and underside to reduce weight. It weighs 49 g and has a centred sensor, which Pat preferred over designs that position the sensor closer to the front.

The mouse is physically ambidextrous, although its side buttons are located on the left side. This means left-handed users may find the button placement less convenient. The cable is lightweight and glides across a desk without creating much drag. Pat described the clicks as pleasant and found the mouse precise and comfortable during use.

The mouse uses a BAMF 2.0 26K optical sensor and includes RGB lighting. The wired model is priced at $99 Australian, while a wireless version is available for $149 Australian.

Gaming mouse pad

The included large Pro gaming mouse pad has a rubber underside to help prevent movement on the desk. Although it arrived rolled up, it stayed flat once placed down. Pat found the Model O2 Mini moved smoothly across its surface.

GMMK 3 HE keyboard design

The GMMK 3 HE is a black 75% Hall Effect mechanical gaming keyboard with a substantial feel. It connects via USB-C and includes support for both Windows and Mac layouts, with alternative keycaps supplied for Mac users.

The keyboard includes removable keycaps and switches, along with a removable top case, rotary knob, switch plate, gaskets and bottom case. This modular design allows users to customise or replace many of the keyboard’s components. The package also includes a USB cable, screwdriver, keycap and switch pulling tools, spare keycaps and spare switches.

The keyboard has per-key RGB lighting, a rotary volume control and a mute function. Pat replaced selected keys with the supplied white Aura keycaps, retaining some of the original black and yellow accents.

Software and gaming features

Glorious software provides controls for polling rate, input latency, lighting, custom key bindings and actuation. The actuation point can be adjusted on a per-key basis, while switch calibration is available after changing switches. Dead zone settings are also included.

The keyboard supports an 8,000 Hz polling rate. It also includes a rapid trigger feature, which dynamically actuates and resets keys based on when they are pressed or released. These settings are aimed particularly at users who want detailed control for competitive gaming.

During gaming and general use, Pat reported fast responsiveness and no perceptible lag. He also found the keyboard’s sound smooth and relatively subtle.

Everyday use and limitations

The compact 75% layout takes up less desk space, but it changes the position and size of some keys. Pat found the delete, page up, page down and end keys difficult to locate, particularly because he uses the delete key frequently. The right-hand Control key is also absent, which affects his Control plus K video-editing shortcut.

The Function key can be mapped to another key, although doing so means losing the original Function-key position. The GMMK 3 HE costs $319 Australian, placing it towards users who are specifically interested in customisation and Hall Effect features.

TechManPat’s conclusion

I would keep the GMMK 3 HE on my desk because its responsiveness, comfort and customisation outweigh the layout compromises for me. I also found the Model O2 Mini very light and comfortable, and I would use it every day if I preferred a wired mouse. For typists, I think the keyboard’s switches are pleasant to use, and for users wanting a wireless version of the mouse, the extra $50 provides that option.
