Wireless Ergonomic Trackball Mouse – Work Smarter, Hurt Less

If wrist pain, cramped desks, or endless mouse-dragging are slowing you down, the Nulea M505 Wireless Ergonomic Trackball Mouse is your answer. Instead of moving the whole mouse, you control the cursor with a smooth 44mm index finger trackball — keeping your wrist stationary, reducing strain, and giving you precise control in even the tightest workspaces. Whether you're coding, designing, or just grinding through spreadsheets, this mouse makes every hour at the desk more comfortable.

Connect via Bluetooth or 2.4GHz USB receiver, and enjoy up to 60 days of battery life on a single USB-C charge. Available in Green and Black.
