2pcs Wireless USB Handheld Thumb Trackball Mouse with Laser Pointer — 2.4GHz Nano Receiver, 1000 DPI, Ambidextrous Five-Button

Set of 2 handheld finger trackball mice with integrated laser pointer for presentation use. The thumb-controlled ball lets you move the cursor without moving your wrist, helping to cut strain and lower the risk of repetitive stress injuries during long sessions. Connectivity is via a 2.4GHz nano USB receiver with plug-and-play setup — no drivers required and reliable link up to 10 meters. The contoured, dolphin-shaped body is symmetrical for comfortable use in either hand and features an accessible five-button layout for universal operation. Designed for stationary use, these trackballs free up desk space and work without a mousepad on uneven surfaces, laps, or tight areas. A high-precision 1000 DPI sensor provides smooth, accurate cursor control with adjustable sensitivity suited to detailed graphic work, spreadsheet navigation, and everyday computing.
