Overview
The Mercury K1 is GravaStar's 75% layout wireless mechanical keyboard with an aluminum alloy body, hot-swappable linear switches, and gasket-mounted sound dampening, offered here in an Opaline White finish.
The 75% layout (79 keys) keeps the arrow keys and a few navigation keys while dropping the numpad, a middle ground between a compact 60% board and a full-size keyboard. GravaStar pairs its own switches with Kailh, rated at 40g actuation and 1.5mm pre-travel, and makes them hot-swappable, so the stock feel is not the only option if a buyer later wants to try different switches.
- 75% layout, 79 keys, aluminum body
- Hot-swappable Kailh linear switches
- Gasket mount, 5-layer sound dampening
- USB-C / Bluetooth 5.0 / 2.4GHz wireless
Who it's for
Suits someone building a white-themed desk setup who wants a mechanical keyboard with software-level RGB and macro control across PC and Mac, and who values a quieter, dampened typing sound over a louder clicky board. Less suited to anyone who wants a full numpad or who has no interest in RGB software and lighting layers.
Pros and cons
- Hot-swappable linear switches for a customizable feel
- Gasket mount with 5-layer sound dampening
- 8000mAh battery supports extended RGB use
- Works over USB-C, Bluetooth 5.0, or 2.4GHz wireless
- 75% layout drops the numpad
- Full customization relies on companion software
Performance notes
A 5-layer sound-dampening stack under a gasket-mounted plate is what governs the typing feel here, cutting impact vibration and giving the linear switches a described creamy rather than clacky sound. The 8000mAh battery is large for a keyboard this size, meant to support extended RGB use across its wired USB-C, Bluetooth 5.0, or 2.4GHz wireless connections without frequent charging.
