Corsair M75 Air

Name: Corsair M75 Air
Brand: Corsair
SKU: 42845

Manufacturer: Corsair

The Corsair M75 Air is a right-handed wireless gaming mouse built around a lightweight 60g frame and a tri-mode connection setup covering 2.4GHz wireless, Bluetooth 4.2, and wired USB. It carries eight fully programmable buttons, including three dedicated side buttons, and supports RGB lighting alongside a single onboard memory profile for storing custom configurations. The mouse runs on a rechargeable battery and can remain in use while plugged in for charging.

At the core of the M75 Air sits the Corsair Marksman sensor, which spans a DPI range from 100 to 26000 DPI with adjustable stepping and tracks at up to 650 IPS with a maximum acceleration tolerance of 50G. The polling rate sits at 1000Hz, and the mouse ships with extra weights for those who want to fine-tune the feel beyond its base 60g. Physical dimensions come in at 128mm long, 65mm wide, and 41.6mm thick, with a two-year warranty included.

Pros

Tri-mode connectivity covers 2.4GHz wireless, Bluetooth 4.2, and wired USB, offering flexible setup options
All 8 buttons are fully programmable, allowing complete customization of the entire button layout
Rated battery life of 100 hours on a single charge reduces the need for frequent recharging
The mouse can be used while charging, so a low battery does not interrupt sessions
Extra weights are included in the box, letting users adjust the feel beyond the base 60g
A dedicated DPI switching button allows quick on-the-fly sensitivity adjustments without entering software

Cons

Only one onboard memory profile is available, limiting how many configurations can be stored directly on the mouse
Lacks a profile switching button, so swapping stored profiles cannot be done directly from the mouse
Does not support wireless charging, requiring a physical cable connection to recharge
The battery is non-removable, so it cannot be swapped out when depleted
Right-handed orientation only, making it unsuitable for left-handed users
No gesture support is available

Who is this for?

This mouse is well-suited to right-handed users who want flexibility in how they connect their peripherals, as the tri-mode setup covering 2.4GHz wireless, Bluetooth, and USB accommodates a range of desktop and multi-device workflows. The 100-hour battery life combined with the ability to use the mouse while charging makes it a practical choice for long sessions where interruptions are unwanted. Users who prefer to fine-tune their setup will also appreciate the included extra weights and the full suite of eight programmable buttons, which offer a degree of physical and functional customization suited to gaming or productivity-heavy environments.

Who is this NOT for?

Left-handed users will find this mouse entirely unsuitable given its strictly right-handed ergonomic design. Those who rely on switching between multiple saved configurations on the fly will be limited by the single onboard memory profile and the absence of a profile switching button, making it a poor fit for users who regularly move between different systems or sensitivity setups. Additionally, users who prefer or require wireless charging will need to accommodate a wired charging cable, which may not align with a cable-free desk setup.
