Corsair M55 RGB PRO Mouse Review


In our limited time with the Corsair M55 RGB PRO, we have used it as our main mouse in both daily computing work, as well as while gaming. In both environments, the overall shape and feel of the M55 was quite comfortable. Though slightly large in our hand, the M55 is definitely not the largest mouse we have ever used, nor is it the smallest. The evenly curved body of the M55 lends itself to being more of a palm grip design, though fingertip and claw grips were comfortable as well.


The build quality is exactly what we have come to expect from our Corsair peripherals; solid but not clunky, lightweight but not flimsy. The lightly textured plastic body felt good to our hand, and the rubber side surfaces gave us a good grip on the mouse without any sticky feeling or rough discomfort. Accessing the two thumb buttons was very easy and convenient, and their placement put them right in reach of our thumb. We did however find ourselves clicking the opposite side’s thumb buttons quite often during our testing. This wasn’t really an issue at all, as we had not enabled all side buttons in iCUE, and the button presses were not performing any unwanted actions. This could definitely become an issue if you had all side buttons enabled, and were not careful to avoid errant button presses.


Moving on to gaming performance, we played our fair share of Apex Legends and Fortnite Battle Royale rounds with the M55. The accuracy of the PAW3327 sensor was spot on, and at no time did we feel like it wasn’t keeping up with us, or not accurately translating our moves into on-screen actions. The use of the two thumb buttons was great in Apex Legends, where we have them bound to our special abilities for easy access. These two buttons were also mapped in Fortnite to some of our building options, for quick defensive wall creation, and offensive ramp deployment. Having access to these additional buttons without removing your hand from it’s resting place on the keyboard or mouse is a great advantage. Finally, the M55 is very light, weighing in at just 86g. This can be either a plus or a minus, depending on your personal preference, and with no adjustable weight system, the M55 is catered to those that favor a featherweight device.

Final Thoughts

Billed as a mouse designed for everyone, the Corsair M55 RGB PRO makes a concerted effort to be comfortable for both left and right-handed users. And not to leave anyone out, Corsair provides the same set of features no matter which hand is using the mouse. With other symmetrical mice, not all features are available on each side. This can leave gamers with a mouse the may fit well, but just doesn’t deliver all the features that the M55 does.

With eight programmable buttons, and the ability to assign various macros and action to said buttons, the M55 proves to be a versatile and highly configurable mouse. With full support for Corsair’s iCUE, the M55 RGB PRO offers custom RGB lighting and the ability to sync with other Corsair products, and multiple customizable DPI settings and on the fly switching.


The M55 RGB PRO isn’t out to break the bank either. With an MSRP of $39.99, this mouse is on the low side of the gaming mouse price range, while still offering a ton of great features to everyone. If you are on the hunt for a left-handed mouse that gives you access to features not found on other symmetrical mice, or even if you are a right-handed gamer in the market for a new mouse, definitely check out the Corsair M55 RGB PRO. Solid features, increased accessibility and comfort, along with solid component choices earn the Corsair M55 RGB PRO an 8 out of 10.
