Product Description

The WhatGeek Galaxy80 is an 88-key mechanical keyboard kit designed for users who want a customizable typing experience with a solid build. It suits hobbyists and enthusiasts who prefer hot-swappable switches and value a durable, aluminum case. Its wireless and wired connectivity options make it flexible for various setups, while its gasket mounting aims to improve typing comfort.

Build Quality

The Galaxy80 features a CNC-machined aluminum case that provides a sturdy and heavy feel. Its gasket-mounted design uses foam and multiple sound-dampening pads to reduce impact and vibration, resulting in a quieter and more flexible typing experience. The keyboard’s textured finish supports long-term durability.

Typing Experience

The gasket mount combined with Poron and other foam layers softens keystrokes and minimizes noise, which benefits users seeking a less harsh typing feel. The keyboard supports hot-swappable 3-pin and 5-pin MX-style switches, allowing easy customization without soldering. South-facing RGB LEDs offer smoother and brighter backlighting, adjustable via key combinations.

Connectivity and Compatibility

The Galaxy80 supports wired USB Type-C and wireless 2.4 GHz connections, providing versatility for different environments. It is compatible with major operating systems including Windows, macOS, Linux, Android, and iOS, making it suitable for multi-platform use.

Trade-offs

  • The keyboard is relatively heavy at 1.6 kg, which may reduce portability.
  • As a barebones kit, it requires users to source and install switches and keycaps separately, which may not suit beginners.
  • Battery life and wireless latency details are unknown, which could affect wireless reliability expectations.
