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

Hear the Mercury V75 HE difference.
The Mercury V75 HE delivers a refined acoustic signatureโdeep, 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 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 โ0.125ms.

Precision Trigger, Rapid Response, Enduring Performance
GravaStar Customized HE Switches
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 Pointโ
Eliminate the slowest part of input lag: the initial key press travel before activation. With โ0.1-3.6mm adjustable trigger depthโ (in 0.1mm increments), tailor each key to your playstyleโshallow 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 Triggerโ
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 โfluid, rapid-fire key repeatsโideal for gaming scenarios requiring split-second reactions (e.g., FPS aim, MOBA skill shots).

Last Keystroke Prioritization (LKP) + Snap Clickโ
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"โresetting 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"โexecute rapid combos, skill shots, or direction changes with zero delay.
Semi-Aluminum Construction
Durability Meets Modern Designโ
GravaStar V75 blends rugged durability with sleek aesthetics through its innovative โsemi-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 V75โs hot-swappable magnetic switches let you redefine your typing experienceโswap 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 V75โs enhanced acoustic foam system minimizes keystroke vibrationsโdelivering a crisper, more satisfying sound and a smoother typing feel. Whether youโre 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

Iโve been using the GravaStar V75 HE mainly for Dota 2, and it has completely blown me away. First off, the design is absolutely stunningโit looks futuristic, premium, and stands out on my desk like no other keyboard Iโve owned. Photos honestly donโt do it justice.
Performance-wise, this keyboard is on another level. The input speed is insanely fast, and in Dota 2 that makes a real difference. Skill casts feel instant, last-hits are more precise, and quick reactions during team fights feel effortless. The Hall Effect switches are incredibly smooth and responsive, giving me a competitive edge I can actually feel in-game.
Build quality is solid, typing feels satisfying, and it stays comfortable even during long gaming sessions. If youโre a competitive gamerโespecially a Dota 2 playerโand you want both top-tier performance and a jaw-dropping look, the GravaStar V75 HE is 100% worth it.
Love it look feel function all amazing thanks for the promo code to sway my decision just the switches are like 75 bones heck of a deal
This keeb is very unique and has a very cool aesthetic, however there are some slight things that lower it in rating for me. The software is a little confusing and can be a bit finicky but once you start to get the layout is fairly easy to navigate also if you use firefox the software wouldnโt load so i switched to chrome and it worked just fine. The keycaps that came with this kb arenโt the best, the rgb doesnโt shine through the legends so itโs a little hard to type on but thatโs just the keycaps which can be swapped. Overall a great keyboard with a very cool design and the hall effect switches are a huge game changer for fpsโ.
Beautiful keyboard
perfect
Really good and arrived quicker than I thought and sounds amazing
Products are decent. Customer service communication was horrible. Took nearly a month to get my order. I would recommend NOT ordering directly from company, order off Amazon

Took over a month to ship
Mercury V75- Stealth Black
it's probably the best keyboard I've used and if your looking for a competitive keyboard or casual this will do it's overkill for Minecraft though looks sweet and if I didn't have it I would buy it again
The detailing work on the board is sooooooo cool. i honestly can not wait to buy one when i upgrade my setup. and the sound is out of this world. I know i could buy a better sounding one to what I like. but the detailing and the software has dragged me in.
Iโm lovin it
love it
AMAZING
Good quality, I like the software as well.
Amazing keyboard but it came a bit dirty for some reason, theres already dust on everything inside the box
Bought this to try out the magnetic switches and I was blown away. Only con is the keycaps are impossible to read at night.
Only issue is the key caps, on the balcony model they are almost impossible to read even in good lighting
Its an anazing product I highly recommend
The best keyboard I ever got!!!
Bought it for my boyfriendโs birthday after doing some extensive research, weโre both very happy with it. Arrived pretty quickly. And the switches sounds very creamy. Although the key caps were a bit hard to read being all black.
Not, going to lie.. I usually can't justify spending this much on a keyboard, especially since I still prefer use a controller for gaming, but since I got this keyboard I've been drawn to choosing keyboard first. Besides being the coolest looking keyboards, they're super satisfying and knowing I can change the actuation points is really useful. My only complaint is the software that was a bit of an issue since its accessed online and gives issues with certain browsers. I also had a scary moment where I thought the keyboard was broken cause it tried updating the keyboard but wasn't working and the keyboard itself stopped working. Luckily support helped me figure it out and it's working with no issues since. Does seem like it's a pretty common thing thay happens though so hopefully there's a fix so others don't have to go through the same scare. But yea awesome keyboard and I'm just hoping they'll add some new keycaps to their store so I can switch these out with one of their other cool designs!
I Love this keyboard, the Futuristic look, the backlighting and customizable nature of the keyboard make it a top tier purchase, definitely elevates your entire systems look with the matching blacked out mouse, love the look of the all red or all green with the mouse and keyboard (coming from All Razer Gear and h while I Love those, I Love these as well!) definitely my new favorite gear
Very durable and clean looking product
