BEST WIRELESS MOUSE WITH TRACKBALL: LOGITECH MX ERGO

Trackball mice are an acquired taste, but the MX Ergo’s innovative design may have wider appeal. Its width and shape can accommodate most hand sizes and its responsive thumb-side trackball is easy to use

and control. A removable metal plate on the bottom serves a dual purpose. Its weight keeps the mouse perfectly still on your desk as you rotate the scroll wheel. And it can also be adjusted to tilt the mouse 20 degrees, an angle that puts your arm in a more natural, rested position.

The mouse has eight buttons—including a dedicated precision button that slows the cursor speed so you can make more accurate movements with the trackball—all of which can be customized using Logitech Options software. The mouse connects via an accompanying USB dongle or Bluetooth, and Logitech claims its battery can go four months on a single full charge. The only downer is it’s not ambidextrous, so southpaws will have to look elsewhere.
