Overview
Switching between its three connection modes, Bluetooth, radio wireless and wired USB-C, lets this compact mechanical keyboard follow the user across devices. A gasket structure and a pre-lubed switch set shape the typing feel, and a CNC knob adds a dedicated control.
Customization is the reason to look at it: switches can be swapped without soldering, keys are programmable, and the knob and RGB lighting suit a desk built around a gaming setup. The limitation is missing detail, with battery capacity, battery life and operating system support absent from the listing, plus a plastic case.
Who it's for
A gamer or writer with limited desk space who moves between a PC, laptop and phone and likes tuning how switches feel. Buyers who want a full-size board, or who need confirmed compatibility with a specific operating system, should check first.
Pros and cons
- Three connection modes
- Pre-lubed linear switches
- Programmable keys and RGB lighting
- Keycap puller included
- Battery life not listed
- Compact layout lacks a number pad
Performance notes
Typing feel comes from the linear Coconut switches, their factory lubrication and the gasket mounting that cushions the plate. Wireless response depends on the mode chosen: wired USB-C avoids radio lag and charges the battery, while Bluetooth suits switching between devices. Swapping switches changes the feel without replacing the board.
