Key Features

True 8kHz Polling Rate
An 8000Hz USB polling rate paired with 256kHz key-position scanning is utilized to reduce input delay to approximately 0.125ms, allowing actions to register with exceptional speed.

Magnetic Jade Pro Switch Technology
The GravaStar x Gateron Magnetic Jade Pro Switch is engineered with a 0.005mm precision structure. Adjustable trigger depth allows every key to respond according to user preference, supporting both fast-paced and deliberate input styles.

Adjustable Actuation Point
A customizable trigger depth in 0.1mm increments (0.1mm–3.5mm) is supported, allowing each key to be tuned for speed, precision, or a balance of both depending on the game or task.

Dynamic Rapid Trigger System
Keystrokes are activated and reset dynamically based on travel distance instead of fixed preset points, enabling fluid, rapid-fire input repetition.

Last Keystroke Prioritization (LKP) + Snap Click
Directional changes are smoothed by prioritizing the most recent keypress. When multiple keys are pressed simultaneously, deeper actuation is favored for improved accuracy.

Rapid Trigger Mode
Re-press delays are minimized by eliminating key “stiction,” allowing keys to reset instantly during upward travel.

Semi-Aluminum Construction
A durable aluminum frame is paired with a lightweight premium plastic base, creating a modern aesthetic while maintaining strength and portability.

Hot-Swappable Magnetic Switch Support
Switches can be replaced without soldering, offering compatibility with select TTC and Gateron magnetic Hall Effect models for versatile customization.

5-Layer Acoustic Foam
Keystroke noise and vibration are reduced through multiple internal foam layers, creating a crisp, dampened sound profile suitable for gaming or office environments.

16 RGB Modes with Dual-Zone Control
Lighting customization is supported with 16 dynamic modes across keys and ambient side zones, allowing hue, saturation, and brightness adjustments.
