The Razer RZ03-04370400-R3G1 is a full-size (100%) gaming keyboard with a German QWERTY layout in black. It supports multiple connection modes — USB, RF wireless, and Bluetooth — offering flexibility for desktop and mobile setups. The keyboard uses optical key switches for fast actuation and includes RGB LED backlighting to adjust illumination per key and create customizable lighting profiles. Designed by Razer for gaming use, it combines performance-oriented switch technology with a familiar full-size layout.

Advantages

Multiple connectivity options (USB + RF Wireless + Bluetooth) allow seamless switching between wired precision and wireless convenience. The full-size form factor preserves a dedicated number pad and standard function keys, while RGB LED backlighting improves visibility in low-light conditions and supports personalized lighting setups.

Suitable for
