Nulea M501 Wireless Trackball Mouse

Bottom line: The Nulea M501 Wireless Trackball Mouse ($27.19 on Amazon as of 2026-10-06): Thumb-operated trackball moves the cursor without wrist or arm travel; main trade-off: none of the 6 buttons are programmable - no custom macro or app-specific mapping.

Manufacturer description

The Nulea M501 puts a thumb-operated trackball where you expect a mouse, so your cursor moves without your wrist and arm doing the work. That matters if you use a keyboard tray, a couch, a bed, or a desk too cluttered to swing a mouse across - the M501 tracks from a single fixed footprint on almost any surface. The angled shell keeps your palm in a natural resting position through a long session, and adjustable DPI lets you dial cursor speed to your monitor setup rather than living with one fixed sensitivity. Connectivity is where the Nulea trackball earns its keep for multi-machine setups…

Nulea's keyboards & mice lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Up to 3, using either Bluetooth or the included 2.4GHz USB receiver. A button on the underside cycles between the paired devices.

Inside the bottom of the trackball mouse itself, so it travels with the unit instead of getting lost in a bag.

No. Nulea states that none of the 6 buttons on the M501 are programmable, including the back and forward buttons, which keep their default browser navigation functions.

Does it take AA batteries?

No - it uses a built-in rechargeable battery. Charge it fully before first use, use the included cable, and plug into a computer USB port or a 5V charger. Do not use a fast charger.

Will it work with a Mac?

Yes. Nulea lists compatibility with PC, laptop, Mac, and Windows systems over both Bluetooth and the USB receiver.
