## Long description

The Lenovo 4X31R64490 is a full-size wireless keyboard and mouse combo designed to enhance office productivity through a stable and reliable 2.4 GHz RF wireless connection. This set features a professional QWERTY UK layout with responsive scissor-switch keys, providing a comfortable and quiet typing experience suitable for long work sessions. The inclusion of a dedicated Copilot key allows for quick access to AI-powered assistance in Windows, while the spill-resistant design and adjustable tilt legs ensure durability and ergonomic comfort in any workspace.
Advantages
This peripheral set stands out due to its sustainable construction, utilizing 65% post-consumer recycled plastic for both the keyboard and the mouse. The low-profile, 2.5-zone keyboard layout includes a full numeric keypad and dedicated media controls, which streamline daily tasks and improve workflow efficiency. Users benefit from the long battery life of up to 15 months for the keyboard and 18 months for the mouse, reducing the frequency of maintenance. Furthermore, the ambidextrous design of the mouse ensures it is comfortable for both left- and right-handed users, while the optical sensor provides precise navigation with 1600 DPI resolution.
Suitable for
General office work and administrative tasks
Professional environments requiring a clean, cable-free desk
Users who prefer a full-size keyboard with a numeric keypad
Individuals looking for sustainable and eco-friendly office equipment
When it may not be suitable
This keyboard and mouse combo may not be ideal for competitive gaming, as it is optimized for office productivity rather than high-speed response times or advanced macro customization. Additionally, users who require Bluetooth connectivity will need to look for alternative models, as this device relies exclusively on a 2.4 GHz RF wireless receiver.
