GravaStar Mercury V75 Lite HE

Step into ultra-responsive esports performance with the GravaStar Mercury V75 Lite HE. Sporting a compact 75% form factor, the keyboard preserves dedicated arrow keys and the essential function row while clearing maximum mouse-swiping area on your desk pad. It is enclosed in GravaStar’s signature exoskeleton-inspired transparent crystal chassis (Crystal Black / Onyx), allowing the vibrant per-key RGB lighting to shine brightly through the body and translucent UV-printed keycaps.

The core of the Mercury V75 Lite HE lies in its contactless Hall Effect magnetic switches. Unlike traditional mechanical switches that rely on physical leaf contacts, these magnetic switches measure key travel continuously with 0.01mm precision. This enables Rapid Trigger (RT) technology: keys reset the instant you lift your finger by even a fraction of a millimeter, allowing for rapid counter-strafing, instant movement halts in Valorant and CS2, and lightning-fast skill execution without waiting for the switch to rebound. Players can customize actuation points between 0.1mm and 4.0mm in fine 0.1mm increments, alongside features like Dynamic Rapid Trigger and Last Keystroke Prioritization (LKP/Snap Click).

To handle this precision without bottleneck, the keyboard operates at a native 8000Hz polling rate, transmitting inputs to your PC up to 8,000 times per second to achieve an ultra-low 0.125ms latency.

Acoustics are also dialed in. The V75 Lite features a gasket-mounted design backed by a 5-layer acoustic foam system (incorporating PORON sandwich foam, IXPE switch pads, PET sound-dampening sheets, PORON bottom foam, and silicone padding). This eliminates internal chassis ping and hollow reverb, delivering a clean, solid, and satisfying typing sound right out of the box.
