Ducky One 3 Classic SF Keyboard Gaming USB Mechanical 67 Keys RGB

Ducky One 3 Classic SF Keyboard Gaming USB Mechanical 67 Keys RGB is a wired 67-key compact mechanical keyboard designed for gaming and everyday typing. It features true PBT double-shot keycaps with a frosted finish, hot-swappable Kailh sockets, detachable USB Type-C connection and customizable RGB backlighting. The keyboard uses a dual-layer PCB and multi-layer acoustic padding with an EVA foam layer under the PCB to improve sound quality and reduce unwanted noise.

Advantages

The keyboard’s true PBT double-shot keycaps provide legends that will not fade and a surface that resists shine and stains. An optimized weight distribution and lowered case height increase stability during intense use. Hot-swapable Kailh sockets allow quick switch changes without soldering. Dual-layer PCB offers improved signal stability and longer lifespan, while multi-layer padding and EVA foam enhance acoustics and noise reduction. Detachable USB Type-C with 1000 Hz polling ensures responsive input, and adjustable two-step feet give three tilt angles for ergonomic preference.

Suitable for

• Gaming (competitive and casual)
• Fast typing and programming

How to use

Use the keyboard’s built-in controls to adjust RGB brightness, speed and color. Place the keyboard on a stable surface and set the two-step feet to the preferred tilt angle for comfort.

Recommendations

For prolonged keycap appearance and performance, clean the frosted PBT keycaps with a soft, dry or slightly damp cloth and avoid harsh chemical cleaners. When changing switches, power off the system or disconnect the cable to prevent accidental input. Use the lower case height and weight balance for stable gaming sessions and the sound-dampening layers to achieve a quieter typing profile.
