Gaming accessory maker Gravastar dropped one of the hottest looking, and specced up keyboards of 2025 on us late last year with the launch of the Mercury V75 Pro, and with Christmas/New Year out of the way, I’ve finally gotten a chance to take a look at the keyboard – and frankly I wish I’d been using it sooner.

Priced at $429, the Gravastar Mercury V75 Pro Cyberpunk brings high-end features including 8K polling for extremely low latency, and Magnetic Hall Effect switches on the keyboard, which brings extreme durability, ultra-fast response times, as well as allowing for user controlled actuation points. 

The Mercury V75 Pro is a compact ‘75%’ format keyboard, an even more compact option than the TenKeyLess (TKL) format keyboards reducing the keys on-board to 84, and moving the arrow keys and removing Home, End and Insert keys.

It’s also one of the grooviest looking Cyberpunk style keyboards I’ve had the pleasure to use. 

So, how does it go? In a word: Awesome. Want more? Let’s get into it.

Hardware and Design

As you’d expect the box for this wild looking keyboard has a funky wild design, that makes it a real shame to hand off to the recycling bin, but inside is where the exciting parts are at and there’s a lot inside. 

Everything you need in the box including a sturdy USB Type A to Type-C cable, keycap puller and four spare Gravastar x Gateron Magnetic Jade Gaming Switches, and a cleaning brush and cloth to keep it all clean.

Out of the box, the first impressions are good. The keyboard has a solid, premium feel to it thanks to an aluminium frame, gasket-mounted hotswappable PCB and layers of foam sandwiched together for a smooth, crisp experience and a plastic base does save some weight – but it’s sturdy and feels phenomenal.

The weight of the keyboard itself, combined with rubberised pads on the base and  the (absolutely awesome) claw-like legs at the back make for a super solid platform which doesn’t move around on your desk – a great feature when playing some intense games.

The claw-legs at the rear move in and out – out for flat on the desk, or retracted to hold the keyboard up at an angle to make it easier and more comfortable to play if flat isn’t your thing.

Getting it up and running is easy, plug the cable in and go – almost. Where you plug the USB-cable in the back, you’ll see two switches: Win/Mac and RT/N. 

The Win/Mac switch simply changes some layout under the hood to better fit the Command button vs Windows button etc. while the RT/N switch changes you between Gaming (Rapid Trigger – RT) and Office (N) – with the N setting disabling Rapid Trigger to make typing a  little easier using NKRO. 

The 75% keyboard layout is easy to get used to. The function keys at the top are easy to reach and the volume switrch in the top right is brilliant, easily reachable with good feedback – push to go up, pull back to lower, and push to instantly mute. 

The keycaps themselves have a cup like top to rest your fingertips in, and are PBT double-shot keycaps – PBT (Polybutylene terephthalate) plastic which uses a  two-stage process to include the letter in the moulding so it doesn’t wear off – and with the artwork on these keys – that’s awesome, because if you like this aesthetic, you don’t want it wearing off.

The tops of the keys are opaque with no light bleed, with the RGB lighting coming through the translucent sides of the keys so you don’t have light blasting up at your eyes in a dark environment.

The keycaps are easily removed with the keycap puller then able to easily access and pull the switches, the keycaps then easily slip back on and stay on with no give when you place them back.

The Hall-Effect switches are one of the key benefits of the Gravastar Mercury V75 Pro with the tiny magnets inside able to register key presses with only a tiny amount of pressure if you configure it in the settings.

This magnetic actuation makes for less wear, so your connectors don’t get slowly worn down over time – so it’s just as responsive on day 1000 as it is the first time you use it.

If anything DOES go wrong with one of the switches, you have four spares in the box, and you can replace them in under a minute. 

The only outlier on the keyboard for me was an LCD display above the right arrow key. The display shows the Gravastar logo, which turns multicoloured when CapsLock is engaged. I’d love to be able to change the logo to something custom – but can’t find any settings to do so.

The keyboard has full multi-zone RGB lighting throughout with dual-zone to let you configure the keys differently to the side lighting, with full saturation and hue control – all configured in the settings.

Config and Setup

Once you’re plugged in and typing, you’ll want to configure your brand new beast and there’s a lot to configure with this keyboard if you want to.

There’s no software to download, instead it’s all on-line on the Gravastar website with the first connection bringing a firmware update before letting you into a full config menu.

Here you can do everything you want, actuation points which you can adjust in 0.1mm increments between 0.1mm–3.5mm and you can also set dead zones as a whole, or per key so you can avoid accidental keypresses. 

You can also configure the RGB lighting with 16 modes to choose from – which also allows you to change colour and more.

You can configure hot keys and macros so your in-game response is faster, and you can even emulate a controller to send linear signals from the keyboard. Wild. 

Gravastar have included pre-programmed configurations for popular games like Counterstrike Go (CS:Go) and ‘Fearless’ – what Valorant is called in China – or you can set up multiple different custom configurations.

In effect, you have full control over your keyboard. It’s actually kind of overwhelming to start with, but just gets better the more you dig into the settings.

Final Thoughts

Holy heck this thing is good. 

The amount of work that’s gone into this keyboard is amazing. The 8k Polling is blisteringly fast, and while the smooth typing and instant response took a minute to get used to, the touch typing in office mode is insane, and the response in games is, in a word, stunning.

The overall look of the keyboard is divisive, but I am absolutely sold on the quality and response, and the configurability of the Gravastar Mercury V75 Pro in their online tool means you can set it your way.

In short, if you’re at all serious about gaming, this is a must-look for any gamer.
