Hexgears Purple Rain M4 Mechanical Keyboard - Creamy 99-Key Gasket

In this review of the Hexgears Purple Rain M4 mechanical keyboard, the bottom line is simple: this is a compact, comfortable 99-key board for users who want a tactile, customizable typing and gaming experience without a full-size footprint. The M4's standout feature is its gasket structure combined with pre-lubed Kailh Green linear switches, which together deliver a consistent, damped feel that reduces finger fatigue during long sessions. For builders and hobbyists the hot-swappable PCB and open-source firmware make personalization straightforward, while everyday users get a reliable, ergonomic number-pad equipped layout.

Key Features

• 99-Key 96% Layout: Retains number pad and arrows in a compact footprint, preserving functionality while saving desk space.
• Gasket Structure: The gasket-mounted design provides a softer, more cushioned keystroke and improved acoustics for longer typing comfort.
• Kailh Green Linear Switches: Fast, light linear switches are pre-lubed to reduce scratchiness and provide smooth, consistent actuation across the board.
• Hot-Swappable PCB: The hot-swap support for 3-pin and 5-pin switches lets you change switches without soldering to tailor the feel and sound.
• Open-Source Firmware: Customizable firmware allows remapping and macro creation for personalized layouts and workflow shortcuts.
• Detachable Type-C Connection: Wired Type-C connectivity ensures stable response and broad compatibility with Windows, MacOS, Android, PS, Xbox, and laptops.

Who It's For

The Hexgears M4 is ideal for gamers and office users who want a near-full layout with a number pad but prefer a smaller case than a full-size board. Its pre-lubed Kailh Green linear switches and gasket mounting make it a good fit for typists who value a smooth, muted keystroke and reduced finger fatigue.

Enthusiasts and hobbyists who enjoy modding will appreciate the hot-swappable PCB and open-source firmware for remapping and macros. Those who need a compact tenkeyless without a number pad, or prefer clicky switches for audible feedback, should look elsewhere.
