Corsair M55 RGB Pro Review! Excellent Gaming Mouse

Written by William

You’ve just finished meticulously routing cables in your new battle station and are basking in the subtle glow of RGB LEDs, but your setup is not ready yet. Your old generic mouse has served you well, but its bargain-bin sensor is holding you back. Your crosshairs are unsteady and trying to select individual units is frustrating.

Worst of all, it disrupts the svelte aesthetics of your new rig. Fortunately, Corsair has recently released a family of gaming mice with something to fit anyone’s needs and budget.

These newest additions are the ambidextrous M55 RGB Pro, the shape-shifting Glaive RGB Pro, the weight-tunable Nightsword RGB, and the free-roaming Ironclaw Wireless RGB — all of which we will be covering here.

The M55 RGB Pro is the most basic option of the bunch but basically does not mean it skimps on features. Its highlights include a contoured ambidextrous design, a total of 8 programmable mouse buttons, and on-the-fly DPI cycling.

The Glaive RGB Pro targets users who want more control over the comfort of their mouse. It provides three magnetically swappable thumb grips to alter its shape. Two of the options allow you to choose between a wider or narrower grip while the third features a full winged thumb rest. This can be a nice feature for indecisive gamers or shared workstations, but most users will probably find the thumb grip that works for them and stick to it.

The M55 RGB PRO is a great lightweight mouse for the fast-paced gameplay of FPS games. It’s comfortable to grip and fits my hand better than most of the other mice out there that I’ve tried.

  • Comfortable
  • Sleek design
  • Smooth glide
  • Affordable


  • Slightly spongy click
  • Side grips feel cheap
  • The scroll wheel is hard to reach with fingertip grip

The M55 RGB Pro is comfortable underhand, too. Although its tear-drop shape may feel strange to those who haven’t used an ambidextrous mouse before, you quickly become used to it. The matte shell is also pleasantly grippy, boasting a rough surface that gives an improved sense of control. The side grips don’t impress quite as much, but I suppose that’s where the M55’s lower cost becomes apparent—these are made of a rubber that feels like cheap plastic. They do the job, though. What’s more, they’re definitely the outlier. This is an affordable mouse that masquerades as something more premium.


Are all 4 thumb buttons programmable at the same time? And can you make them control windows volume in the software?

You can certainly map the entirety of those buttons at one-time, through our issue software. You can also set them all up to control media keys.

Am I able to replace the buttons on the right side? I don’t want them there when I game. or are they permanent?

They wouldn’t be removable, unfortunately, although they shouldn’t bother you at all.

Does it work with PS4?

Afraid not, none of our mice are tested to work with the PS4.
