What we like about Gravastar Mercury K1

  • Unique sci-fi 'exoskeleton' aesthetic that stands out from typical gaming keyboards.
  • Sturdy build quality featuring an aluminum alloy frame that feels premium and durable.
  • Excellent typing feel and 'creamy/thocky' sound profile due to the gasket-mounted design and multiple foam layers.
  • Long-lasting 8,000mAh battery that can last weeks on a single charge.
  • Highly responsive GravaStar x Kailh linear switches that are well-suited for both gaming and productivity.
  • Versatile tri-mode connectivity (Bluetooth, 2.4GHz wireless, and USB-C wired) with easy switching between Windows and Mac.
  • Vibrant dual-zone RGB lighting with highly customizable independent systems for keys and the keyboard edges.

What we don't like about Gravastar Mercury K1

  • Proprietary companion software is often described as clunky, difficult to use, and limited in features.
  • The spacebar on the standard K1 model can sound and feel hollow compared to the rest of the keys.
  • Software is currently only compatible with Windows, making it hard for Mac users to customize lighting or macros.
  • The volume rocker is not programmable, which limits its utility for some users.
  • Side-printed legends on the keycaps can be difficult to read if you are not a touch typist or are looking from certain angles.
  • Limited stock switch options; it typically only ships with one type of linear switch out of the box.
  • The unique 'alien leg' design on the Pro version can make the keyboard less portable and bulkier for travel.

Verdict

The GravaStar Mercury K1 is a 75% layout mechanical keyboard featuring a distinctive die-cast magnesium alloy hollow-frame design for enhanced heat dissipation and durability. It offers versatile triple-mode connectivity (Bluetooth 5.0, 2.4GHz wireless, and USB-C), hot-swappable PCB sockets, and pre-lubed linear switches paired with internal sound-dampening foam layers. While it boasts a 1000Hz polling rate and customizable RGB lighting for a premium gaming experience, its high price point, significant weight, and lack of a dedicated dust cover for the open-frame chassis are notable drawbacks.
