What we like about Gravastar Mercury K1 Lite

  • Bold and unique 'alien' futuristic design that stands out from generic keyboards
  • Excellent 'creamy' or 'thocky' sound profile due to 5 layers of sound-dampening foam and gasket-mounted design
  • Smooth and responsive typing experience with pre-lubed GravaStar x BSUN linear switches
  • Versatile tri-mode connectivity (2.4GHz wireless, Bluetooth 5.0, and Wired USB-C)
  • Highly customisable with a south-facing hot-swappable PCB supporting 3-pin and 5-pin switches
  • Vibrant and bright RGB lighting, enhanced by transparent PC keycaps in some models
  • Practical features like a 4,000mAh battery with an integrated battery level indicator (Fn + B)

What we don't like about Gravastar Mercury K1 Lite

  • Proprietary companion software is often described as difficult to navigate, 'trash,' or Windows-only
  • Keycap quality can be inconsistent, with some users finding the legends or slogans like 'Be Cool. Play It' to be poorly designed
  • The lightweight PVC frame can feel flexible or exhibit 'twist' compared to the heavier aluminium Pro version
  • Lacks the physical volume control knob found on the standard K1 and K1 Pro models (replaced by a Delete key)
  • The transparent PVC material is highly prone to showing fingerprints and smudges
  • Limited stock switch options for users who prefer tactile or clicky feedback out of the box

Verdict

The GravaStar Mercury K1 Lite is a 75% layout (80-key) mechanical keyboard featuring a striking, futuristic PVC skeleton design with transparent PC keycaps and per-key RGB lighting. Built on a gasket-mounted structure with a 5-layer sound-dampening foam system, it utilizes custom GravaStar x BSUN linear switches (40gf actuation, 2mm pre-travel) to deliver a soft, 'creamy' typing experience. Main pros include its versatile tri-mode connectivity (2.4GHz, Bluetooth 5.0, and wired USB-C), hot-swappable 3/5-pin PCB, and a substantial 4,000mAh battery providing up to 666 hours of life with lights off. However, common cons include a lightweight plastic chassis that may exhibit more flex than aluminum counterparts and proprietary customization software that is currently limited to Windows users.
