Ergonomic 55mm Trackball

The Nulea M512 is a wireless trackball mouse built around a stationary 55mm ball that minimises hand movement during long sessions. Its ambidextrous layout automatically swaps button functions for left or right-handed use with a single mode switch. Connectivity covers Bluetooth and 2.4 GHz wireless, pairing with up to three devices such as laptops, tablets or smartphones. A rechargeable battery removes the need for disposable cells.

Suited to Multi-Device Desks

This mouse fits users who want precise cursor control without sweeping a traditional mouse across the desk, making it practical for graphic design, video editing or general office work on any surface including beds or couches. The four adjustable DPI levels (400, 800, 1200, 1600) cover browsing through detailed tasks. Buyers who prefer a conventional sliding mouse or who need more than seven programmable buttons should consider other form factors.

Simple Pairing and Maintenance

Pairing is handled through standard Bluetooth menus or the included 2.4 GHz USB receiver; no proprietary software is required for basic operation. The trackball pops out for occasional cleaning of the sensor and bearings, which keeps tracking consistent. The supplied wrist rest attaches magnetically and helps reduce forearm strain during extended use.

Questions about this item

Does the M512 need a USB port for the 2.4 GHz receiver?

Yes, the 2.4 GHz link uses a USB receiver; Bluetooth pairs directly without one.

Can I keep my existing wired mouse connected while the M512 is paired via Bluetooth?

Yes, the M512 pairs independently over Bluetooth so a wired mouse stays active on the same computer.

How do I confirm the DPI has changed when I press the DPI button?

The cursor speed shifts through 400, 800, 1200 and 1600 DPI levels; test by moving the 55 mm trackball the same distance and noting the pointer travel.
