Nulea M501 Rechargeable Wireless Trackball Mouse — Ergonomic Thumb-Control, Smooth Precise Tracking, Connects to 3 Devices (Bluetooth or 2.4G USB Receiver) — PC/Laptop/Mac/Windows

Comfort-first thumb trackball: The Nulea M501 shifts cursor control to a low-friction thumb ball so you don’t have to move your wrist or forearm. Its angled shape keeps the palm in a natural position to reduce muscle strain and provide all-day comfort. Precise, adjustable tracking: Built-in adjustable DPI lets you fine-tune cursor sensitivity for accurate control and smoother pointer movement across nearly any surface. Ideal for tight workspaces — messy desks, couches, beds or small writing boards. Rechargeable and multi-device ready: This wireless trackball is rechargeable and supports connections to up to 3 devices via Bluetooth or the included 2.4G USB receiver. A bottom-mounted switch lets you toggle devices quickly, and the 2.4G USB receiver is stored in the mouse’s base when not in use. Compatible with PC, laptop, Mac and Windows systems.
