The new standard office mouse - Logitech MX Master 4

Quick Overview

The Logitech MX Master 4 mouse is a premium productivity device featuring a 240Hz polling rate via its USB-C Bolt dongle, haptic feedback on the thumb gesture panel, and high-quality materials, although the presenter notes the setup/pairing process was frustrating and the mouse lacks a charging brick in the box.

Key Points: The Logitech MX Master 4 utilizes a USB Type-C Bolt dongle for connection, supporting Bluetooth Low Energy 5.1. The mouse weighs 150g (0.33 lb) and features a premium build with aluminum/plastic layers and PTFE feet for smooth gliding. A key feature is the Haptic Sense Panel on the thumb rest, which provides vibrations when interacting with the Actions Ring or for important event notifications. The main scroll wheel supports both line-by-line scrolling and hyper-fast free-spinning, which can be toggled via the Mode Shift button. The presenter measured the polling rate at a peak of 135Hz and an average of 125Hz over Bluetooth, which they considered a slight disappointment compared to the previous MX Master 3S. The presenter found the initial software setup and pairing process frustrating, noting that the mouse does not come with a charging brick. The mouse is ergonomically designed for productivity workflows, allowing extensive customization of buttons and gestures via the Logi Options+ software.

Context: The video presents a review and unboxing of the Logitech MX Master 4, Logitech's latest high-end productivity mouse, succeeding the popular MX Master 3S. The presenter focuses on new features like the haptic feedback panel, the updated scroll wheel modes, and the overall ergonomics and build quality compared to previous models, while also detailing the accompanying Logi Options+ software setup.

Detailed Analysis

The presenter unboxes and reviews the Logitech MX Master 4 mouse, noting that while it is an exciting premium productivity tool, the setup process was frustrating. The mouse weighs 150g and features premium materials, including a layered construction with a transparent layer over grey plastic, and PTFE feet for smooth gliding. The presenter measured the polling rate over Bluetooth at an average of 125Hz and a peak of 135Hz, which they felt was slightly disappointing compared to the MX Master 3S. The mouse supports USB Type-C charging (though no charging brick is included) and connects via Bluetooth Low Energy 5.1 or the Bolt USB-C dongle. A major new feature is the Haptic Sense Panel, which provides tactile feedback (vibrations) when interacting with the Actions Ring or for specific notifications, with intensity adjustable from Subtle to High (the presenter preferred Medium or Low). The main scroll wheel retains its signature feature of switching automatically between line-by-line scrolling and hyper-fast free-spinning when flicked fast, which the presenter found excellent for quickly navigating long documents or code. The Logi Options+ software allows deep customization of all buttons and gestures, including mapping them to specific applications, though the presenter noted that they still prefer the haptic feel of the Steam Deck controller's trackpad over the mouse's haptic feedback for certain actions.
