Gravastar Mercury V75 CyberFlux 75% Hall-Effect Magnetic Gaming Keyboard

The GravaStar Mercury V75 CyberFlux is a 75% wired gaming keyboard built on GravaStar's custom UFO magnetic Hall Effect switches, finished in the bold green-on-black CyberFlux colourway (sold in some markets as the "Star Core" edition): a blacked-out skeletal frame, lime-green and smoke keycaps, and vivid green backlighting that glows through the exposed chassis. It brings esports-grade speed together with GravaStar's unmistakable cyberpunk styling, so it performs as hard as it looks.

At its core is a true 8000Hz USB polling rate with just 0.125ms latency and a 256kHz channel scan rate, so a keystroke registers almost the instant your finger moves. Because the switches are magnetic rather than mechanical, the actuation point is fully adjustable across the full 3.5mm of travel with 0.005mm Rapid Trigger resolution. Dynamic Rapid Trigger, SOCD / Snap Click and Last-Keystroke Prioritization deliver the split-second counter-strafing and rapid-fire repeats that make Hall Effect boards the format of choice for CS2, VALORANT and other fast shooters.

The 75% layout keeps dedicated arrow keys and a multifunction CNC-milled volume knob while trimming the numpad for more mouse room. A semi-aluminum build, gasket-mounted plate and five-layer acoustic stack (plate foam, IXPE switch pads, acoustic film and bottom foam) give a deep, controlled "thock" rather than a hollow rattle, and the UFO switches are hot-swappable, so you can retune the feel without soldering.

Dual RGB light systems wash green across the keys and through the skeletal chassis, and everything is configured from a zero-install web driver: actuation, Rapid Trigger, SOCD, key remaps, macros and lighting, straight from your browser on Windows or macOS.
