TweakTown found that the Gateron Red Nano linear switches deliver a smooth, creamy typing feel with acoustics that are quiet and rattle-free. The keyboard features an impressive 4000mAh battery providing up to 1200 hours of runtime when backlighting is turned off, alongside a hot-swappable rotary knob module for customizable system control. However, TweakTown pointed out a lack of per-key lighting adjustments, with side accents serving only cosmetic purposes, and noted the knob is wobbly and can pop off easily. This compact 75% layout suits users seeking portability and multi-platform compatibility but may disappoint those requiring precise dial feedback or granular lighting customization.

Gateron Red Nano switches deliver low-profile speed
TweakTown found that the Gateron Red Nano linear switches provide one of the best typing experiences available in a low-profile mechanical keyboard. These custom-developed switches offer a total travel distance of 3.5mm with an actuation point located at approximately 1.7mm.
The smoothness and creamy consistency of these switches stand out as a primary reason for the keyboard's high performance rating. The linear nature of the Red Nano switches ensures that keystrokes are quiet and free from echo or rattling sounds during rapid typing sessions. This acoustic profile makes the NuPhy Air75 V3 an excellent choice for users who require a silent yet tactilely responsive input device.
4000mAh battery supports 1200 hours of runtime
The keyboard is equipped with a substantial 4000mAh internal battery that provides up to 1200 hours of continuous usage when the backlighting features are completely turned off. This extended battery life ensures that users can rely on the wireless functionality for weeks or even months without needing to connect the USB-C cable for recharging.
The combination of a large capacity cell and efficient power management makes this device highly suitable for remote workers or travelers who frequently disconnect from their primary charging stations. The longevity of the battery significantly reduces the downtime associated with maintaining a wireless peripheral, allowing for uninterrupted productivity across different environments.
Hot-swappable knob offers customizable system control
TweakTown noted that the inclusion of a hot-swappable rotary knob module adds significant versatility to the keyboard's design. This feature allows users to easily customize their volume controls or scrolling functions by swapping out the physical dial and keycap combination without requiring specialized tools.
The ability to replace the knob highlights NuPhy's attention to detail in creating a highly adaptable peripheral. Users who frequently adjust system audio levels or navigate through documents can benefit from this dedicated hardware control, which is positioned prominently on the top rightmost section of the board for immediate access.
Lacks per-key lighting adjustments limits customization
A notable limitation identified by TweakTown is the absence of per-key lighting adjustments, which restricts users from creating complex illumination patterns across the board. While the keyboard features north-facing RGB-LED backlighting that provides a clean and uniform glow under each keycap, individual control over specific keys is not supported.
Additionally, the side accents on the chassis serve purely cosmetic purposes rather than functioning as programmable lighting elements. This lack of granular customization may disappoint enthusiasts who prefer to fine-tune their desk aesthetics or use specific color codes for different functions within a single layout.
Wobbly knob module detracts from premium feel
Despite the innovative design of the rotary dial, reviewers have pointed out that the knob itself exhibits noticeable wobble during rotation. This physical looseness can be distracting for users who expect a tight, precise mechanical feedback when adjusting settings via the dial.
Furthermore, the module is prone to popping off easily if subjected to excessive force or accidental bumps while typing. This fragility undermines the otherwise robust build quality of the aluminum top case and requires users to handle the knob with extra care during daily use.
Compact 75% layout suits space-constrained desks
The NuPhy Air75 V3 utilizes a compact 75 percent ANSI layout that retains essential function keys and arrow clusters while eliminating the numpad. This form factor is ideal for users with limited desk space who still require full access to navigation controls without sacrificing typing comfort.
Tom's Guide highlighted the keyboard's compatibility with macOS, Windows, Linux, Android, and iOS devices, making it a versatile choice for multi-platform setups. The streamlined design allows for easy portability, fitting seamlessly into laptop bags or travel kits for professionals who work across different operating systems.
Intuitive software simplifies macro programming
TechBroll praised the NuPhy IO web-based customization software for its streamlined and intuitive interface. This digital tool allows users to program macros, adjust key mappings, and update firmware without navigating through complex menus or installing heavy desktop applications.
The accessibility of the web-based platform ensures that even novice users can quickly personalize their typing experience. By removing the friction associated with traditional keyboard configuration software, NuPhy has made it easier for owners to tailor the device to their specific workflow requirements.
