Ergonomic 55mm Trackball

The Nulea M512 is a wireless trackball mouse built around a 55mm ball for thumb-driven cursor control. Its ambidextrous shape suits left or right-handed users who prefer stationary pointing over traditional mouse movement. Adjustable DPI settings provide precise control for office work, creative tasks or general computing. The silver finish gives it a clean, professional appearance on any desk.

Replaces Conventional Mice

This trackball replaces a standard mouse when desk space is limited or when wrist strain makes sliding a mouse uncomfortable. The jump is worth it for users who want to keep their arm still while navigating large screens or multi-monitor setups. It connects via Bluetooth or 2.4GHz wireless, so it works with laptops, desktops and Macs without extra dongles. Buyers who need a second simultaneous pointing device or a dedicated scroll wheel may find this design limiting.

Simple Wireless Setup

Pairing is straightforward: enable Bluetooth on the host or plug the 2.4GHz receiver into a USB port and the mouse connects automatically. The built-in rechargeable battery removes the need for disposable cells and charges over USB. Common issues include occasional cursor drift if the ball or sensor window collects dust, which is resolved by wiping the ball and the optical aperture. Some users report a brief learning curve for fine movements if they have never used a trackball before.

Questions about this item

What desk space does the 55mm trackball and 6.46 x 5.75 x 3.03 inch body need?

The mouse measures 6.46 by 5.75 by 3.03 inches and weighs 15 ounces, so it sits flat on any desk without a separate mount or clearance zone.

How do I pair the mouse over Bluetooth and 2.4GHz, and which step do users miss?

Charge the battery first, then toggle the mode button to Bluetooth or 2.4GHz, put the mouse in pairing mode, and select it in the OS — skipping the initial charge is the common mistake.

When will the rechargeable battery need replacement after 12 months of daily use?

The built‑in rechargeable cell is rated for roughly 12 months of typical daily use before its capacity drops enough to require a full replacement.
