If you use the exact same desk space to navigate daytime productivity and late-night gaming sessions, you already know it’s an endless tug-of-war for desktop real estate. Do you crowd your workspace with two completely separate peripherals, one for typing spreadsheets and one for clicking heads? Or do you try to find a middle ground, usually ending up with a device that feels mediocre at both?
Historically, choosing a wireless mechanical keyboard has meant picking your poison. You either sacrifice speed and responsiveness for the sheer convenience of a cordless desk, or you watch your battery drain halfway through a crucial gaming session because of overly aggressive lighting and high polling rates. For a long time, tech nerds and professionals have simply accepted these compromises as the cost of doing business.
GravaStar has stepped into this frustrating void with a bold solution: the Mercury K98 Pro mechanical keyboard. Having used this keyboard extensively as my daily driver for over a month, I can confidently state that the era of desk compromises might finally be over. By packing high-end wireless performance into a full-size 98% layout (crucially keeping the often-missed number pad) it delivers the ultimate dual-purpose setup. It is a stunning, highly functional piece of hardware that has entirely changed how I interact with my workstation.
The Story: Science Fiction Meets Everyday Functionality
GravaStar has carved out a devoted cult following by flawlessly blending heavy sci-fi, mecha aesthetics with everyday consumer technology. They design for users who refuse to separate top-tier performance from unapologetic personality.
That’s why I admire the Mercury K98 Pro, the way once glance instantly shows just how the standard peripheral market has become stale. Most keyboards fall into two distinct camps: they are either boring, plastic rectangles designed for an office cubicle, or they are gaudy gaming boards that look entirely out of place when you are on a video call with clients. GravaStar recognised that gamers grow up, have professional careers, and need functional tools, but they still want hardware that makes a statement.
Engineered specifically to eliminate the dreaded “wireless penalty,” this keyboard was built to prove that you do not need a cord to achieve competitive speeds, and you do not need to sacrifice aesthetics to get a reliable, long-lasting battery.

The Mechanics: How It Works and How It Feels
The immediate impact of the K98 Pro is visual. The style is genuinely next level. Housed in a premium, CNC-machined aluminium skeletonised chassis, it looks like a beautiful cyberpunk creature resting on your desk. The exposed framework gives it a raw, industrial presence. It is one of those rare pieces of technology that looks so good, you almost want to hang it on a wall rather than type on it.
Customising the look and feel is also surprisingly effortless. Repairing it or swapping the visual style is much easier than I anticipated. The model I received came with an extra set of yellowish-coloured keycaps, which I swapped in almost immediately to replace the default transparent black. The resulting contrast gave off a massive Cyberpunk 2077 vibe that perfectly suits a modern desk environment, highlighted by an immersive three-sided ambient underglow that looks incredible in a dimmed room.

It’s important to note the device comes with all the tools you need to do this as well as keep it nice and clean in and around the keys. These peripherals all feel premium and thoughtful.
But a keyboard has to do more than look pretty. One of the standout features that completely won me over is the simple way you can swap between Windows and Mac modes directly using the built-in screen and menu controls. My daily workflow involves a split ecosystem: my professional work setup relies entirely on a Mac, but my gaming setup is actually Linux-based. Historically, finding hardware that transitions seamlessly between these two operating systems without endless software re-pairing is a nightmare. Having the ability to flick a switch and instantly optimise the keyboard for either environment is a massive quality-of-life improvement.
Then there is the 1.65-inch Smart TFT display built directly into the board. This screen provides real-time visual feedback, and the features you access through it are perfectly implemented. What makes it even better is that the display and lighting are configured via a web driver. This means you do not have to install bloated, resource-heavy desktop software just to change a GIF on the screen or adjust the lighting profiles.

When the workday ends and the gaming begins, the performance is flawless. The K98 Pro delivers a blistering 8000 Hz polling rate across both wired and 2.4 GHz wireless connections, achieving a near-instantaneous 0.4 ms wireless response time. I have been putting this keyboard through its paces in fast-paced titles like CS2, massive warfare scenarios in Battlefield 6, and the atmospheric tension of Hellraiser Revival. In every single scenario, the responsiveness was absolute. There is zero discernible input lag, and every action feels immediate and precise.
Supporting this performance is a massive 8000mAh battery. This allows the keyboard to yield up to 228 hours of life on a single charge. You can easily game and work for weeks without ever reaching for a charging cable. I’d actually completely forgotten that it needed to be charged at all.
Finally, the typing experience itself is superb. Utilising GravaStar’s proprietary UFO linear switches combined with a five-layer sound-dampening system, every keystroke delivers a deep, satisfying sound right out of the box. There is no hollow echoing, just smooth, tactile feedback that makes long typing sessions a genuine pleasure.
The Comparison: Stacking Up Against the Competition
When evaluating how the Mercury K98 Pro compares to the rest of the market, it clearly stands in a league of its own especially for hybrid users.
If you look at dedicated gaming keyboards from mainstream brands, you often find high polling rates but terrible battery life, forcing you to keep them plugged in anyway. They also frequently rely on cheap plastic chassis materials that creak under pressure. On the other end of the spectrum, premium mechanical keyboards geared toward professional typists often lack the 2.4 GHz wireless speed required for competitive shooters, leaving you frustrated when you load into a match of CS2.
The K98 Pro bridges this gap flawlessly. It offers the heavy, premium build quality and acoustic refinement of a custom enthusiast board, combined with the extreme low-latency performance of an esports peripheral. Having the 98% layout is the icing on the cake, giving you the productivity of a number pad without taking up the massive footprint of a traditional 104-key board.
The Final Verdict
A keyboard is one of those devices that blends into your daily life and is easy to take for granted. The GravaStar Mercury K98 Pro retails for $499.99 AUD ($579.99 NZD), placing it more in the premium category of computer peripherals. However, when you factor in the sheer quality of the materials, the massive battery life, the flawless wireless performance, and the fact that it effectively replaces the need for two separate keyboards, the value is undeniable.
It perfectly balances premium tactile execution with standout desktop presence. Whether you are crunching data on a Mac during the day or dominating lobbies on Linux at night, this keyboard adapts to your needs without missing a single beat. I highly recommend the GravaStar Mercury K98 Pro. It is a stunning piece of technology that will completely elevate the way you work and play.
