Cidoo V21 Mechanical Keyboard

The Cidoo V21 Number Pad is a compact mechanical keypad designed for users who need a customizable numeric input device.

Its multiple connectivity options and comfortable typing experience make it useful for both desktop and mobile setups.

Key Features

• VIA programmability allows remapping keys, creating macros, and customizing RGB lighting, enabling a personalized workflow.
• Metal rotary knob with RGB lighting adds control options beyond standard keys, useful for volume or scrolling adjustments.
• Triple connectivity modes (wired USB-C, Bluetooth, 2.4GHz wireless) offer flexibility for different environments and devices.
• 1000mAh battery supports extended wireless use, reducing interruptions for charging.

Build Quality and Typing Experience

• Gasket-mounted design uses a PORON foam strip to reduce key impact noise and provide a softer, more comfortable typing feel.
• Dye-sublimated PBT keycaps resist wear and fading, maintaining legibility and texture over time.
• South-facing LEDs minimize interference with keycap legends and improve lighting consistency.
• Aluminum alloy knob and PC plate contribute to a sturdy construction without excessive weight.

Connectivity

• Wired mode via USB-C ensures low latency and stable connection for tasks requiring responsiveness.
• Bluetooth and 2.4GHz wireless modes provide cable-free use, suitable for mobile or clutter-free setups.
• Switching between modes requires manual selection, which may interrupt workflow briefly.

Trade-offs

• Limited to 20 keys plus one knob, which may not cover all users’ shortcut needs.
• Unknown battery life duration under wireless use, so actual runtime may vary.
• No information on OS compatibility beyond VIA support, which may affect use on some systems.
• Absence of hot-swappable switches limits switch customization without soldering.
