The Genius DX-101 in Black is a wired optical mouse designed for reliable daily use across various computing tasks. It features an optical sensor with a resolution of 1200 DPI, providing smooth cursor movement, and includes three standard buttons consisting of the left, right, and a middle scroll wheel for easy navigation. Its black plastic body is shaped with a comfort contour and an ambidextrous design, meaning it fits naturally in either hand. Measuring 64.27 x 110.25 x 37.85 mm and weighing approximately 83 g, the device remains lightweight enough for long sessions without causing fatigue. A 1.5m USB cable ensures you have enough reach to connect it to your PC or laptop, which should be running Windows 8, 10, 11 or Mac OS X 10.8 and later.
