Like New Ergonomic Wireless Trackball Mouse (Bluetooth & 2.4G)

Received it as a gift 2 months ago but only tried using it twice. I am used to the traditional mouse and could not get used to trackball style, so it’s just been sitting in the box. It is in absolute pristine, like-new condition and works perfectly. The original price is around 40$. Features: - Ergonomic Design: Great for reducing wrist pain/fatigue since you move the cursor using the red thumb trackball instead of moving your whole arm. - Multi-Device Connectivity: Supports up to 3 devices. Can connect via 2.4GHz USB wireless dongle or through two different Bluetooth channels (BT1/BT2). Great for switching between a laptop, desktop, or tablet. - Adjustable DPI: Has a dedicated button on top to change pointer speed.
