The SVEN KB-C3500W is a wireless keyboard and mouse set designed for comfortable daily computing on Windows systems. Both devices connect via a single 2.4 GHz nano USB receiver, allowing you to work freely within a 10-meter range without the clutter of cables. The membrane keyboard features a wave-like surface and adjustable folding legs to help you find a natural typing angle, while its 106-key layout includes English, Russian, and Ukrainian characters. To speed up your workflow, it offers two dedicated buttons for the calculator and search functions, along with 12 additional shortcuts accessible via the Fn modifier for controlling volume and media playback. A built-in indicator lets you know when the batteries are running low, and the keys are rated for over 20 million clicks. Complementing the keyboard is an optical mouse with an ergonomic casing that includes a thumb rest and a rubberized scroll wheel for a more secure grip. You can adjust the tracking precision between 800, 1200, and 1600 DPI depending on your task, and a physical On/Off switch helps preserve the battery when the mouse is not in use. Weighing only 71 grams and featuring buttons tested for 3 million clicks, this mouse provides a lightweight and responsive experience. The set comes in a classic black finish and includes the necessary AA batteries to get you started immediately.
