Rechargeable Wireless Ergonomic Trackball Mouse — Thumb-Controlled, Precise Tracking, 3-Device (Bluetooth & 2.4G)

Comfort-first thumb control: This ergonomic trackball mouse uses a smooth thumb-operated ball so you move the cursor without shifting your wrist or arm. Its optimized angle keeps your palm in a natural position to help reduce muscle stress and offer all-day comfort. For best results, please fully charge the bluetooth trackball mouse before your first use. Precise, adjustable tracking: The trackball delivers accurate cursor movement and fine control with adjustable DPI, letting you work confidently on nearly any surface and in tight spaces like a cluttered desk, couch, bed, or a small writing board on a chair. True wireless multi-device connectivity: Connect up to 3 devices via bluetooth or USB dongle and switch between them using the button on the bottom to streamline your workflow. The 2.4G USB receiver is stored at the bottom of the wireless trackball mouse. Rechargeable battery and charging notes: A built-in rechargeable battery removes the need for disposable cells. Please use the included charging cable and avoid fast chargers — charge from a computer USB port or a 5V charger for safe, proper charging. Six-button productivity layout: Designed with an elegant curved shape and thoughtful ergonomic details, this trackball mouse includes back and forward buttons for easier navigation. Note: All buttons on this wireless trackball mouse are not programmable.
