GravaStar – Mercury V75 Pro

Where Industrial Design Meets Acoustic Aesthetics, we engineer high-end peripherals that look as good as they perform. The Mercury V75 Pro is our first Hall Effect Keyboard, designed to redefine 75% layout standards with cutting-edge magnet technology, Gasket comfort, and RGB artistry.

True 8kHz Polling Rate

The V75 Pro boasts a blazing 8000Hz USB polling rate, paired with 256kHz key-position scanning, delivering a True 8kHz polling experience that slashes keyboard latency to a near-instantaneous ​0.125ms.

GravaStar x Gateron Magnetic Jade Gaming Switch

Engineered for industry-leading 0.005mm precision and adjustable trigger depth (0.1mm- 3.5mm), they eliminate lag and keep you in control. Perfect for clutch plays in CS2, precise aiming in Valorant, or building a setup that stays sharp. This keyboard uses south-pole-down (S-pole down) Hall Effect switches and currently does not support north-pole-down (N-pole down) configurations.

Adjustable Actuation Point​

Eliminate the slowest part of input lag: the initial key press travel before activation. With ​0.1-4.0mm adjustable trigger depth​ (in 0.1mm increments), tailor each key to your playstyle—shallow presses for lightning-fast combos, deep presses for intentional precision. Perfect for reducing accidental taps and optimizing response times in fast-paced games.

Dynamic Rapid Trigger​

Say goodbye to fixed reset points. This feature dynamically adjusts activation/deactivation points based on key travel distance, not predefined limits. Keys engage instantly on press and release immediately on release, enabling ​fluid, rapid-fire key repeats—ideal for gaming scenarios requiring split-second reactions (e.g., FPS aim, MOBA skill shots).

Last Keystroke Prioritization (LKP) + Snap Click​

LKP ensures smooth directional changes by prioritizing your last-pressed key, critical for games like Valorant or Apex Legends. Snap Click intelligently resolves simultaneous key presses: it favors deeper presses and auto-resets shallower ones, so you never miss a command. Together, they eliminate "input chaos" and sharpen your competitive edge.

Durability Meets Modern Design​

Gravastar V75 Pro blends rugged durability with sleek aesthetics through its innovative ​semi-aluminum construction: a sturdy metal frame forms the backbone, ensuring structural integrity even during intense gaming marathons, while a premium plastic base adds a lightweight, modern touch to your desk setup.

Silence Meets Sensation

Gravastar V75 Pro’s enhanced acoustic foam system minimizes keystroke vibrations—delivering a crisper, more satisfying sound and a smoother typing feel. Whether you’re crushing FPS combos or typing up reports, this multi-layer design ensures every press feels deliberate, every click stays quiet, and your focus stays sharp.
