Cidoo V21

The Cidoo V21 Number Pad is a compact mechanical keypad designed for users who need a customizable numeric input device. It suits gamers, programmers, and professionals who want to tailor key functions and lighting through VIA software. 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.
