Overview

The Logicool M575SPd is a wireless trackball mouse built for people who want to keep their arm still while working. Instead of sliding the whole body across the desk, you roll the ball with your fingers, so the device stays in one spot and the wrist rests at a natural angle. The sculpted shape and angled scroll wheel are designed to suit a wide range of hand sizes.
This version focuses on quiet operation, with click noise substantially reduced compared with the earlier trackball it replaces. Connectivity has also been reworked around Bluetooth and the Logi Bolt receiver, and the receiver ships in the box. Tracking uses Logitech Advanced Optical Tracking with a selectable range from 400dpi to 2000dpi.
Power comes from a single AA battery, and the manufacturer rates battery life at up to 18 months, which suits a mouse that lives permanently on a desk. If you want a compact pointing device that reduces arm travel and keeps noise low in shared rooms, this is the kind of product to look at.

Connectivity & Compatibility

You can pair the M575SPd over Bluetooth or through the bundled Logi Bolt receiver. With Bluetooth, the supported systems are Windows 10 or later, macOS 11 or later, iPadOS 14 or later, and ChromeOS. With Logi Bolt, the listed systems are Windows 10 or later, macOS 11 or later, and ChromeOS.
Logi Bolt is the option to pick when connection stability matters, such as in an office where many wireless devices share the airwaves. Bluetooth is the more flexible route for tablets and laptops that have no free USB port for a receiver, and it makes switching between machines straightforward.
The Logi Options+ software adds Smart Actions, which lets you assign a sequence of shortcuts or functions to a single button. For anyone who repeats the same commands all day, that cuts down on back-and-forth between the mouse and the keyboard.

Product Info

The M575SPd launched on 19 September 2024 and sits in the mid range for trackballs, with street pricing in the mid five-thousand yen bracket. What defines it is the combination of quiet clicks, Logi Bolt connectivity and an ergonomic shell at a price that individual buyers can justify. It is a sensible first trackball for someone who wants to reduce wrist strain without moving to a premium tier.

Best Use Cases

  • People with a cramped desk who cannot spare room to sweep a mouse around: the body stays put while the ball does the work, though it is a poor fit for fast flick-based gaming.
  • Shared offices and meeting rooms where click noise carries: the quiet switches and stable Logi Bolt link keep operation discreet, while those who want a loud, tactile click will find it soft.
  • Anyone who dislikes charging routines: a single AA battery keeps it running for months, so a cable never has to be part of the setup, though very heavy daily use may make a rechargeable model more convenient.
