Introduction
GravaStar is a brand that consistently leans into bold, futuristic design, and the Mercury V75 Hall Effect Gaming Keyboard continues that trend. Featuring a compact 75% layout and Hall Effect magnetic switches, this keyboard is clearly aimed at gamers who want fast response times, deep customisation, and something visually different from the usual minimalist designs.
After spending time using the Mercury V75 for both gaming and everyday tasks, it’s clear that this keyboard isn’t just about looks. It delivers a premium feel and strong performance, while still having a few quirks worth noting.
Unboxing & First Impressions
Opening the box, the Mercury V75 is well presented and securely packaged. GravaStar includes several useful accessories, including a dust brush, switch & keycap puller, and four magnetic switches. These extras are small but appreciated, especially for users who like to keep their gear clean or make minor customisations.
The moment the keyboard is lifted out of the box, its weight is immediately noticeable. It feels solid and substantial, giving the impression of a well-built product designed to stay firmly in place during use. Once on the desk, it doesn’t slide around, even during longer gaming sessions.
Visually, the keyboard stands out. The industrial, sci‑fi‑inspired design won’t suit everyone, but it certainly gives the Mercury V75 a strong identity and makes it a centrepiece rather than something that blends into the background.
Design & Build Quality
The Mercury V75 uses a semi‑aluminium alloy frame paired with GravaStar’s signature skeletal shell. In everyday use, the build feels very sturdy, with no noticeable flex or creaking. This rigidity adds to the overall sense of quality and helps give each keypress a consistent feel.
The 75% layout is a practical choice. It keeps the function keys, arrow keys, and navigation buttons while saving desk space compared to a full‑size keyboard. Transitioning from a larger keyboard was easy, and the layout never felt cramped during daily use.
A rotary knob is positioned in the top‑right corner and defaults to volume control. It feels smooth to turn and quickly became something I used without thinking, especially when switching between games, videos, and music.
Switches, Keycaps & Feel
The Mercury V75 uses Hall Effect magnetic switches, which differ from traditional mechanical switches by using magnets instead of physical contact to register key presses. In practical terms, this means smoother movement and adjustable sensitivity.
From a personal use perspective, the keys feel soft and comfortable under the fingers. There’s a smooth travel to each press, and the keys feel consistent across the board. During longer sessions, the keyboard remained comfortable to use, with less finger fatigue than expected.
The double‑shot PBT keycaps feel high quality and have a slightly textured surface that provides good grip. Larger keys such as Space and Enter are well stabilised and don’t rattle excessively, which adds to the premium feel.
Typing Experience
For everyday typing, the Mercury V75 performs better than expected for a gaming‑focused keyboard. Out of the box, the keys are quite sensitive, and it did take a short adjustment period to avoid accidental presses.
Writing, messaging, and general office tasks felt smooth, and the softer key feel made longer typing sessions comfortable. While it’s not silent, the sound level is reasonable and what you would expect from a performance‑oriented keyboard.
Gaming Performance
Gaming is where the Mercury V75 really comes into its own. The responsiveness of the keys is immediately noticeable, especially in fast‑paced games. Movement inputs feel instant, and quick directional changes are easier to execute compared to standard mechanical keyboards.
The Rapid Trigger feature allows keys to reset as soon as pressure is released, rather than waiting for a fixed reset point. In real gameplay, this translates to smoother movement and faster reactions, particularly in competitive titles where timing matters.
The keyboard’s weight also plays a role here, keeping it stable even during intense moments. It feels reliable and responsive throughout extended gaming sessions.
Software & Setup
Setting up the Mercury V75 is straightforward. It works immediately when plugged in, and installation on both Windows and macOS was simple. Basic functionality is available straight away.
The software allows adjustment of actuation points, key remapping, macros, and RGB lighting. While the interface isn’t the most polished, it’s functional and gets the job done. After initial setup, I rarely needed to revisit it.
RGB Lighting
The RGB lighting on the Mercury V75 is bright and evenly distributed. Colours look vibrant, and the lighting works well with the keyboard’s design. It’s easy to find a preset that suits your setup or to create something more personalised if desired.

Final Verdict

For gamers who want fast response times and a keyboard that stands out visually, the Mercury V75 is a compelling option. It also holds up well for everyday use, making it a versatile choice for users who want both performance and personality in their setup.
