Corsair M55 Wireless

Manufacturer: Corsair

The Corsair M55 Wireless is an ambidextrous mouse built for both gaming and productivity use, offering a lightweight 59 g frame that suits a wide range of hand orientations and grip styles. Its wireless design supports both 2.4GHz and Bluetooth 5 connections, and the removable battery delivers up to 400 hours of runtime, making it a practical choice for extended sessions without frequent recharging.

On the performance side, the optical sensor covers a range from 200 to 24000 DPI with full adjustability, a maximum tracking speed of 300 IPS, and a maximum acceleration of 35G, all at a 1000 Hz polling rate. The mouse includes 6 fully programmable buttons, 2 of which are side buttons, along with dedicated DPI and profile switching buttons, and a single onboard memory profile for storing custom configurations. It carries a 2-year warranty.

  • Battery life rated at 400 hours, reducing the need for frequent recharging
  • Removable battery allows for replacement rather than discarding the mouse when battery degrades
  • Supports both 2.4GHz wireless and Bluetooth 5, offering flexible connectivity options
  • All 6 buttons are fully programmable, covering the entire button set
  • At 59 g, the mouse is notably light, which can reduce fatigue during extended use
Cons
  • Only one onboard memory profile available for storing configurations
  • No RGB lighting for users who prefer visual customization
  • Scroll wheel lacks tilting functionality, limiting horizontal scrolling without button remapping
  • No extra swappable weights included for users who prefer a heavier feel
  • Gesture support is absent, which may limit productivity workflows on certain platforms
Who is this for?

This mouse works well for users who switch between multiple devices or platforms, thanks to its dual Bluetooth 5 and 2.4GHz wireless connectivity. The ambidextrous shape and 59 g lightweight build make it a practical fit for both left- and right-handed users who spend long hours at a desk without wanting added physical strain. The 400-hour battery life and removable battery also suit anyone who needs a reliable, low-maintenance daily driver for mixed gaming and productivity tasks.

Who is this NOT for?

Users seeking deep hardware customization will find the single onboard memory profile limiting, especially in setups where quick switching between multiple configurations is important. The absence of a tilting scroll wheel and gesture support makes this a poor fit for productivity-heavy workflows that rely on horizontal scrolling or multi-touch navigation. Additionally, competitive gamers who prefer a heavier, customizable mouse weight or visual RGB feedback will find the fixed lightweight design and lack of swappable weights restrictive.
