The SVEN KB-C2550W is a wireless keyboard and mouse set designed for a clean, cable-free workspace. Both devices connect through a single 2.4 GHz USB nano receiver, allowing you to manage your desktop without multiple dongles. The keyboard features a low-profile design with scissor switches for a tactile yet quiet typing experience, and its 109-key layout includes English and Russian characters, with the latter highlighted in red for better visibility. To help you work more efficiently, the keyboard includes five quick-access buttons for the calculator and volume, along with twelve multimedia functions accessible via the Fn key. You can easily toggle the multimedia control mode by pressing Fn + Esc. The hardware is compact, measuring 430 x 122 x 21.5 mm, and includes a dedicated power switch to conserve battery life when not in use. Accompanying the keyboard is a symmetrical optical mouse with a 1000 dpi sensor, making it comfortable for both left- and right-handed users. It features three buttons and a durable metal scroll wheel, fitting naturally in the palm with dimensions of 110 x 62 x 31 mm. A low battery indicator on the devices lets you know when it is time to replace the AA and AAA batteries, ensuring your workflow remains uninterrupted.
