Logitech MX Ergo S Advanced Wireless Trackball Mouse USB C - Graphite Review (2026)

An updated take on a proven design

The MX Ergo S keeps the core idea that made the original MX Ergo popular: a trackball body that tilts to reduce wrist strain during long stretches at a desk, aimed at office workers, designers, and anyone recovering from or avoiding wrist discomfort from a standard mouse. What changes in this version is the charging port and some internal refinements, while the ergonomic case shape and control layout stay familiar to existing MX Ergo users. Buyers upgrading from an older Logitech mouse or trackball will find the transition straightforward, since the software and button logic carry over, while new trackball users get the same learning curve as any first switch from a standard mouse to thumb-operated ball control.

USB-C charging and battery life

The standout upgrade is USB-C charging, replacing the older Micro-USB style port used on the original MX Ergo. Logitech states that just one minute of charging provides about 24 hours of use, and the built-in 500 mAh battery is rated for up to 120 days, or roughly four months, on a full charge under typical use. This brings the mouse in line with most current laptops, tablets, and phones that already use USB-C, so buyers no longer need to keep a separate cable style around just for this one accessory. For anyone who has already standardized their desk on USB-C chargers and cables, this is a meaningful convenience over the prior generation.

Comfort, weight, and build

The body measures about 132.5 by 99.8 by 51.4 millimeters and weighs roughly 164 grams without the metal base plate or receiver, or about 259 grams with it attached, letting users choose between a lighter feel or a heavier, more stable base on the desk. The hinge still tilts to 20 degrees, the same angle as the original MX Ergo, positioning the wrist in a more relaxed, handshake-like posture rather than flat on the desk. Logitech also notes the shell uses recycled plastic, a small sustainability detail that does not change day-to-day performance but may matter to environmentally conscious buyers comparing similar-priced trackballs.

Buttons, sensor, and software

Six buttons are customizable through Logitech's Options Plus software, covering shortcuts, application switching, and other assignable actions, matching the original MX Ergo's programmability. The sensor spans a DPI range of 512 to 2048, giving fine control for detailed work at the low end and faster cursor travel at the high end, adjustable via a dedicated button or the software. Connectivity includes Bluetooth alongside Logitech's Bolt USB receiver, an updated wireless dongle standard that replaces the older Unifying receiver used on the original MX Ergo, offering a more secure and modern wireless connection for office environments.

Trade-offs to weigh

The MX Ergo S costs more than both the original MX Ergo and basic entry-level trackballs, a premium buyers pay for the newer charging standard and receiver technology. Like its predecessor, the shape is designed only for right-handed use, so left-handed shoppers looking for a comfort-focused trackball will need to look elsewhere entirely, since no mirrored version exists in this lineup. Buyers who already own the original MX Ergo and are happy with its Micro-USB charging may not find enough new here to justify replacing a working mouse, while anyone buying a trackball for the first time or already on USB-C everywhere else will appreciate the update.
