The GravaStar Mercury K98 Pro Phantom Black Edition (GSK98PRO-GM / 6972448925297) combines alien-inspired futuristic industrial design with high-performance mechanical keyboard engineering. Crafted with an exo-skeleton aluminum alloy frame, this 98-key wireless gaming keyboard is built for gamers, tech enthusiasts, and creators who demand a striking desk aesthetic alongside competitive gaming performance.
Key Features
Sci-Fi Die-Cast Aluminum Frame: Built with a durable die-cast aluminum alloy exo-skeleton chassis in a Phantom Black finish that delivers structural rigidity, stability, and an iconic sci-fi appearance.
Efficient 98% Compact Layout: Retains the function row, dedicated directional arrow keys, and a full number pad in a streamlined footprint that maximizes mouse movement space without sacrificing productivity.
Tri-Mode Wireless Connectivity: Seamlessly switch between ultra-fast 2.4GHz wireless for lag-free gaming, Bluetooth 5.1 for multi-device pairing, and a detachable USB-C wired connection for charging and continuous play.
Hot-Swappable Switch Sockets: Easily swap out mechanical switches without soldering, allowing custom tuning of key switches and typing acoustics to match your preference.
Gasket-Mounted Sound Isolation: Multilayer internal sound-dampening foam and a gasket-mounted internal structure minimize hollow typing ping, delivering a deep, clean, and satisfying acoustic profile.
Vibrant Per-Key RGB Illumination: Features bright, customizable RGB lighting effects with multiple pre-set modes and full per-key backlight customization via GravaStar software.
Long-Lasting Rechargeable Battery: High-capacity internal battery provides extended wireless operation, allowing for multi-day gaming sessions with RGB enabled or weeks of play with lighting turned off.
Performance & Ergonomics
The K98 Pro features durable keycaps with oil-resistant surfaces and clean legends. Coupled with hot-swappable custom linear switches, it offers smooth, consistent keystrokes with minimal wobble for competitive gaming and extended typing sessions.
Design & Compatibility
Fully compatible with Windows, macOS, Android, and iOS devices. Dedicated hardware toggle switches allow for effortless operating system mode switching and quick connection pairing.
Why This Product Stands Out
The GravaStar Mercury K98 Pro stands out with its die-cast aluminum skeleton chassis, 98% full-featured layout, hot-swappable mechanical switches, gasket-mounted sound isolation, and tri-mode wireless freedom.
