The GravaStar Mercury V75 Pro Cyberpunk Keyboard is one of the most interesting keyboards I’ve ever used. Full disclosure, I expected to hate it—but I think I’m in love.
Reviewing tech is a precarious endeavour. It’s a life spent exploring a field made entirely of rabbitholes, any of which can pull you in. Even casual prodding can turn the mundane into a White Rabbit, and before you know it, you’re upside down and sucked in up to the ankles. Totally consumed. That happened to me with mechanical keyboards. My personal Lemiwinks was a powder-blue Epomaker I reviewed earlier this year, but looking back, the adventure it set me on was always leading here: the GravaStar Mercury V75 Pro Cyberpunk, the final boss of mechanical keyboards.
The Mercury V75 Pro Cyberpunk is pure joy. It might be the most unapologetic piece of gamer gear ever made. By rights, that should be a turnoff—gamer styling is awful—but this keyboard is different. It leans so hard into gamer aesthetics that it blows past notions of taste and speaks directly to the heart of your inner 12-year-old. The GravaStar Mercury V75 Pro is functional art. It isn’t content with being just an S-tier gaming peripheral; it’s a toy in its own right, and it demands to be played with.
Functionally, this is a 75% wired-only keyboard equipped with magnetic Hall Effect switches, a gasket-mounted hotswappable PCB, and pudding-style PBT+polycarbonate keycaps, all housed in an RGB-lit aluminum frame that’s packed with sound-dampening foams. If that reads like gibberish, don’t worry—we’ll dig into it. In short, this isn’t your average gaming keyboard; it’s closer to something you’d find in a custom shop or hanging on the wall in some fetishist’s typing dungeon.
“The GravaStar Mercury V75 Pro is functional art.”
We’ll start from the top with the keycaps and work our way down. The Mercury V75 Pro uses SA-profile pudding-style keycaps. They get their name from the pudding cup look: opaque PBT tops paired with translucent polycarbonate sides. The PBT surface has a satiny texture, sculpted into a shallow bowl that naturally guides your fingers to the center of each key. These aren’t shine-through keycaps—the RGB bleeds only through the translucent sides, not through the legends themselves. The stylized legends are applied with dye-sublimation, a process that embeds the print directly into the plastic, so you’ll never have to worry about the text wearing off over time.
The keyboard comes in a few different styles, but for this review, GravaStar provided us with the Cyberpunk edition. What makes it cyberpunk? I have no idea. Overall, the font of the legends and graphical markings gives off more of a Star Trek vibe. The only spot that looks a little Cyberpunky is the arrow keys, which, if you squint, kind of look like part of a skill tree from Cyberpunk 2077.
Premium keycaps are always lovely, but here, it’s what’s underneath them that should have your attention. The Mercury V75 Pro uses 79 Gateron Jade magnetic switches. If you’re new to magnetic switches: welcome to the future; it’s very responsive here. Unlike mechanical switches that rely on copper connectors making contact with each other, magnetic switches use the Hall Effect (HE) to register keystrokes. The Hall Effect registers inputs by pushing magnets towards a tiny sensor.
There are two major benefits to HE keyboards. The first advantage is durability, since they don’t rely on repetitive contact points that wear out over time. The second, and more important, is that they’re far more customizable. Instead of just being on or off, the switch can sense how close the magnet is to the sensor, which means you can dial in actuation through software and decide exactly how deep a press needs to be before it registers.
The Gateron Jade switches feature an adjustable trigger depth from 0.1 to 4.0mm, and each one can be independently mapped. The reset points can also be set dynamically, so instead of having to cross a fixed position before another input can be registered, the reset kicks in as soon as the key starts moving up. Pair that with the keyboard’s blazing-fast 8000 Hz polling rate and 256K scan rate, and you’ve got performance that sits right at the apex of what a gaming keyboard can do.
It all works phenomenally well, but I’m not a fan of how GravaStar makes you set it up. This is the first keyboard I’ve ever owned that uses web-based software. I hate it. To remap keys or customize RGB presets, users will have to use a website. For a premium keyboard, this is a weird choice. It feels sketchy. I was hesitant to use it, preferring VIA support instead. In fact, it even made me miss the austere software that comes with Redragon keyboards.
For most users, the software will never be an issue. Even without adjustments, this keyboard is going to perform exceptionally well. However, this isn’t a device for most people—it’s for keyboard weirdos and power users. Considering the premium price and the intended market, having software you don’t have to bookmark would be a massive improvement.
Performance is all well and good, but let’s be honest—the most interesting thing about the GravaStar Mercury V75 Pro is the design. Love it or hate it, it’s one of the most unique-looking boards money can buy. The skeletonized aluminum frame has a biomechanical vibe, with muscle fibres sculpted into the RGB strips that wrap around the edges. And then there are the mech-spider legs sticking out the back. They’re not just for show—they replace the adjustable feet you’d typically find underneath.
They take some getting used to, but the feet add something I didn’t know I wanted in a keyboard: fidgetability. I catch myself clicking them around constantly. Paired with the clicky push-pull volume switch and the unreasonably satisfying typing noise, the Mercury V75 Pro doubles as an unrivalled stim toy. The toy vibes don’t stop there, either; they permeate every aspect of the keyboard. Even the bottom plate has faux pipes and vents embossed in it, reminiscent of the underside of a die-cast car, and on the Cyberpunk edition, there is even a racing stripe. Because sure, why not? The best way to sum up the aesthetic is Xel’Naga Hot Wheels.
Everything about this keyboard exists for a good time. At first, I cringed a little at the design, but as I used the GravaStar, something happened—my heart grew three sizes, completing my Grinch arc. What I usually can’t stand about gamer peripherals is how they try to look overly sleek or obnoxiously edgy. The GravaStar Mercury V75 Pro takes a wholly different approach; it isn’t trying to be cool, it’s just meant to be fun, which makes it actually cool.
For me, the defining trait of a premium keyboard is whether I look forward to using it. Typing is a chore, and most of the time, I don’t enjoy sitting at my computer—but a quality keyboard can change that. Designing one that injects a little joy into your day is no easy task, yet GravaStar nailed it. Carefully chosen switches and keycaps, paired with high-quality foams and stabilizers, create a typing experience that feels incredible and sounds like music once you find your rhythm. This keyboard is meant to impress your inner child, but to appreciate it truly, you need to have endured the monotony of adulthood.
That may sound like overthinking, but GravaStar built that idea right into the design. There’s a dedicated switch on the back of the frame that puts the keyboard into “office mode,” which disables the rapid-trigger functionality and makes typing easier—a choice that is, in and of itself, hilarious.
Imagining this keyboard in front of a loan officer at a bank makes me laugh. At the same time, I get it. In a professional setting, this thing would be a power move like no other. Picture negotiating a mortgage or renewing your insurance policy, and the clerical worker pulls out a skeletal keyboard with spider legs and flashing rainbow lights—you wouldn’t know how to react. You’d freeze, and as the hypnotic clicking of the Gateron keys settles into a rhythm, you’d be transfixed, confused, and just a little intimidated. You’d accept whatever interest rate they offered first just to escape the AOE of whatever spell you convinced yourself they were casting.
The GravaStar Mercury V75 Pro isn’t without its drawbacks. The software is atrocious, and the included USB cord is downright disappointing for a keyboard that costs over $200. Even so, this is the easiest recommendation I’ve ever made, flaws and all. Of course, that won’t mean much if you’re not on board with the aesthetics, are arachnophobic, or allergic to having a good time—but if you like fun and performance, you won’t find anything else as show-and-tell worthy as the GravaStar Mercury V75 Pro.
