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.

Hear the Mercury V75 Pro difference.
The Mercury V75 Pro delivers a refined acoustic signature—deep, satisfying "thock" at moderate volumes with crisp, responsive feedback. Swap switches or keycaps to dial in your perfect sound. No modding required.
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.

Precision Trigger, Rapid Response, Enduring Performance
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 north-pole-down (N-pole down) Hall Effect switches and currently does not support south-pole-down (S-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.
Rapid Trigger Mode
Rapid Trigger Mode eliminates key "stiction"—resetting keys instantly as they travel upward, so you can re-press and switch inputs faster than ever. No more waiting for keys to "bounce back"—execute rapid combos, skill shots, or direction changes with zero delay.
Semi-Aluminum Construction
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.

Hot-Swappable Design
Tailor Your Keyboard To Perfection
Gravastar V75 Pro’s hot-swappable magnetic switches let you redefine your typing experience—swap out worn switches or experiment with new feels without soldering. While our magnetic switches use advanced Hall Effect technology for precise actuation.
*Compatibility is limited to select TTC Switches and Gateron models (check our website for details).

5-Layer Acoustic Foam
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.

Steady wired connection. One-click game/office mode switch. Works on Win & macOS

Excelente producto
It's being stored right now until my dream built is done. But on looks and feels alone I'd say I made the perfect choice.....the keyboard and mouse is phenomenal.
10/10 keyboard!
It works awesome my nephew loves it
I didn’t really know what this company was until a TikTok pc review dude I watch aim had a discount code and decided to try it out. Definitely one of the best keyboard I’ve ever had. Good quality!
Keyboard works well buttery smooth
Solid
It has a ability to change settings and sensivity and etc that pretty cool and feels pretty solid and great too and it weight so much that im positive that it could survive ww3 and 5 nukes
This is what every keyboard should be like. I want a full s8ze with 10 keys
I love the style, the weight, and how silent it is. I did an unpackaging on my stream and I love everything about it. I love how silent the keys are and how quickly the response is. I have always love your stuff. keep it up!!!
Gravastar as always delivers a top end quality keyboard! Love the colors, finally purple theme, that is me (with purple hair). This is my 4. keyboard, and that says it all! Gravastar har fantastic costumer service too.
Keyboard looks and feels amazing, very clean sound and the volume switch is really cool.
The only issue I would even say, is the Keyboard doesn’t have a stand alone offline program like the Mice do, and when I clicked download on the keyboard updater thing thinking it may be a standalone app, it was immediately flagged as a problem and deleted, the Mouse stand alone app however is fine and installed no issue, just waiting on the Lavender Purple to drop.
Sleek and well designed keyboard, I love the dampened click of the keys. Its suite of customization options will keep me constantly switching it up
The keyboard is absolutely crazy I love it the quality is just top and the typing noise is crazy first at 5/5 Stars never again each other
Amazing work truly a worth while purchase
It is a nice keyboard :)
