WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

Logitech MX Ergo S Advanced Wireless Trackball

What it brings

Thumb control keeps hand movement to a minimum while the hand rests on the sculpted body, and the adjustable 0–20° hinge lets you set the tilt; Logitech sizes it for medium to large hands.
Manufacturer source
Eight buttons, including a tilting scroll wheel and a dedicated Precision Mode button to drop sensitivity on the fly; six are customisable in Logi Options+.
Manufacturer source Manufacturer source
Logitech rates the 500 mAh battery for up to 120 days per charge, and it connects via the included Bolt receiver or Bluetooth 5.2.
Manufacturer source Manufacturer source
Logitech says the S version has 80% quieter clicks than the MX Ergo, plus USB-C quick charging and Logi Bolt; it connects to up to 2 devices via Bluetooth or the included Logi Bolt receiver, switches between them with the Easy-Switch button and supports Logitech Flow.
Manufacturer source

What to check

Right-handed only, and it weighs 259 g with the magnetic base plate (164 g without).
Manufacturer source Manufacturer source
No USB-C cable is included for charging, and the battery is not user-replaceable.
Manufacturer source Manufacturer source
Logitech's own sensitivity figures disagree (512–2,048 dpi versus 100–2,000/4,000), so the DPI range stays unresolved.
Manufacturer source Manufacturer source

Logitech MX Master 4

What it brings

Eight buttons, including a thumb-side Haptic Sense Panel and gesture button, plus a MagSpeed wheel with SmartShift and a horizontal thumb wheel.
Manufacturer source Manufacturer source
Two ways to connect out of the box: Bluetooth Low Energy 5.1 or the included USB-C Bolt receiver (USB-A Bolt receivers are also compatible), with up to three paired devices switched by Easy-Switch buttons or the Actions Ring.
Manufacturer source
Logitech rates the 650 mAh battery at up to 70 days per charge, with three hours of use from a one-minute charge.
Manufacturer source Manufacturer source
Logitech lists haptic feedback for Actions Ring, Smart Actions and Gestures in Logi Options+, plus plugins for Photoshop, Lightroom Desktop and Zoom. Native Windows11 Advanced Haptics requires the update from the end of March2026 onwards and updating mouse firmware through Options+; native controls are in Windows settings.
Manufacturer source
Logitech states its Quiet Clicks have 90% less left and right click Sound Power Level than the MX Master 3.
Manufacturer source

What to check

It weighs150g and Logitech lists Width88.35mm, with a shape sculpted for the right hand; the USB-C charging cable is not included. Its full dimensions retain Logitech’s original Height×Width×Depth labels.
Manufacturer source Manufacturer source
Logitech support lists a 125 Hz report rate over both Bluetooth and the receiver; it is a productivity mouse, not a high-report-rate gaming design.
Manufacturer source
Full haptic and button customisation relies on Logi Options+ on Windows and macOS; Linux, ChromeOS, iPadOS 15+ and Android 12+ get basic functions without software. Over Bluetooth, Logitech lists Windows 11 or later and macOS 13 or later; with the Bolt receiver, Windows 10, 11 or later and macOS 13 or later.
