The GravaStar Mercury V75 Pro CyberFlux is the flagship of the 75% Hall Effect line, finished in the striking green-on-black CyberFlux colourway (sold in some markets as the "Star Orbit" edition). Built on a solid CNC-machined skeletal aluminum chassis with lime-green and smoke keycaps over green RGB, it is the most serious keyboard in the Mercury range: heavier, more rigid and loaded with the features enthusiasts ask for.
GravaStar's custom UFO magnetic Hall Effect switches drive a true 8000Hz polling rate, 0.125ms latency and a 256kHz channel scan rate for near-instant response. Actuation is adjustable across the full 3.5mm of travel with 0.005mm Rapid Trigger resolution, and Dynamic Rapid Trigger, SOCD / Snap Click and Last-Keystroke Prioritization deliver the counter-strafing and rapid repeats competitive shooters live on. The switches are hot-swappable, so the feel is fully yours to tune.
Where the Pro pulls ahead is the build. A full/semi-aluminum chassis, gasket-mounted structure and reinforced carbon-fibre positioning plate make it noticeably more solid than the standard V75, integrated mechanical kickstands set your angle, and the extended ergonomic wrist support keeps long sessions comfortable. A dedicated metal volume knob and a five-layer acoustic stack round out a deep, premium typing sound.
Dual RGB light systems throw green glow across the keys and wrap the skeletal frame, and everything is configured from a zero-install web driver: actuation, Rapid Trigger, SOCD, macros and lighting, straight from your browser on Windows or macOS.
