3pcs 2.4G Wireless Ergonomic Thumb Trackball Handheld USB Mouse

Pack of 3 compact trackball mice with an ambidextrous, dolphin-shaped housing that fits comfortably in either hand. The thumb-controlled trackball lets you move the cursor precisely while keeping your wrist still, helping reduce strain and lower the risk of repetitive stress injuries during long use. Connectivity is provided by a nano USB receiver using a 2.4GHz link; the plug-and-play setup works up to 10 meters without any software installation—great for laptops and crowded workstations. A five-button layout gives easy access to common controls. Because the ball is stationary, you don’t need a mousepad or much desk space—the device performs reliably on uneven surfaces, laps, or in tight areas. Built-in high-precision 1000 DPI sensor with adjustable sensitivity delivers smooth cursor control for detailed graphic work, spreadsheet navigation, and everyday computing.
