GravaStar Mercury K98 Pro blends cyberpunk design with 8,000 Hz wireless speed

GravaStar put the Mercury K98 Pro up for preorder at $259, turning a 98% wireless mechanical keyboard into a full-format pitch for both work and play. The board went live on June 18 at 8 a.m. EST, and GravaStar said it would ship to more than 50 countries through its distribution network.

The K98 Pro leans hard into the company’s cyberpunk identity, with a fully CNC-machined aluminum alloy chassis and a skeletonized look that makes it read more like desk hardware from a sci-fi set than a plain typing tool. GravaStar is framing it as a gaming keyboard and a productivity device for players and creators, and the official product page goes further, calling it a “futuristic centerpiece” and a “hyper-functional tactical art piece.” That is the exact claim the board has to satisfy if it wants to justify its price: the design has to earn its keep once the novelty wears off and the keycaps start taking daily abuse.

Under the shell, GravaStar is pushing harder than aesthetics alone. The Mercury K98 Pro uses the company’s UFO Mechanical Linear switches, which it rates for 70 million keystrokes, and layers in a five-part dampening stack built from Poron foam, IXPE pads, PET film, a slow-rebound Poron base layer, and silicone fill. That combination is meant to shape a deeper, more focused sound than the hollow clang that can sink larger plastic boards. For users who care as much about acoustics as RGB, that matters as much as the look.

The specs keep stacking up. GravaStar says the 8,000 mAh battery can last up to 228 hours with lighting off, or about 19 to 21 hours with RGB and ambient lighting active. It also claims 8,000 Hz polling over wired USB-C and 2.4 GHz wireless, plus Bluetooth 5.4 for tri-mode use, with response times listed at 0.1 ms wired and 0.4 ms wireless. A 1.65-inch TFT display and a web-based driver give the board a more gadget-like feel, while the lighting system pushes it further into showpiece territory.

The market message is clear: GravaStar is not presenting the Mercury K98 Pro as a compromise between style and utility, but as a large-format board that wants both. Its 4.8-star rating from 71 reviews suggests the design-first formula is already finding an audience, and the real test will be whether that cyberpunk chassis delivers enough sound, speed, and battery life to hold its own against less theatrical boards built for the same money.
