The Corsair M55 RGB Pro has very classic lines. No surprise in the design, we are facing a quite sober mouse, with medium dimensions (129 x 67 x 45 mm), visibly designed to be usable by a large majority of sizes and morphologies of hands. “Even if it means making a mouse suitable for right-handers as well as for left-handers, make it as neutral as possible”, said the designers of the brand. Lovers of sobriety will be satisfied, the mouse is not too typed video game and can therefore also be suitable on a workstation rather typed office.

This apparent design simplicity fortunately does not call into question the ergonomics of the mouse. This M55 RGB Pro being rather pleasant to take in hand. However, it promotes efficiency at the expense of comfort, the plastic of the shell being a little rough. However, it has the advantage of not being too messy. Long enough to put the palm of your hand in it, the mouse can also be grasped with your fingertips.

Its edges are deep enough to provide a firm grip between the thumb and the ring finger or index finger. Their elastomeric relief coating contributes to this good grip, despite its relative hardness. Lifting the M55 RGB Pro is thus easy, especially since it weighs only 90 g approximately (with a piece of cable protruding from our scale; 86 g without its cable, according to Corsair). We could have expected even lighter for a wired mouse, at a time when even wireless mice happily pass under the 100 g mark (80 g even for the Logitech G Pro Wireless ) and where certain wired mice fall under 70 g (the Glorious Model O , for example).


The glide is in any case fairly fluid thanks to the 3 PTFE pads glued under the mouse, but risks being a little hampered by the rigidity of the braided USB cord. If the latter seems robust and is not fundamentally annoying, it lacks flexibility to be forgotten, unlike, for example, that of the Model O or the DM1 FPS .

If the fingers fall naturally enough on the buttons, we can regret that the two main buttons are not curved to better accommodate them and keep them centered. The two buttons of each section, for their part, are large enough that the absence of frank separation between them is not disturbing. On the other hand, it is possible that some users inadvertently activate those on the edge opposite the thumb. This is the price to pay for enjoying a totally ambidextrous mouse. But we could have hoped to take advantage of a system of removable buttons to avoid this. 

Questions of reactivity, the mechanical switches associated with the main buttons offer a free click and a good rebound, for rapid actions, to the detriment, however, of discretion, these being fairly audible. We appreciate their endurance announced at 50 million activations. Mechanical too, the switches associated with the slice buttons do not deteriorate either and are less noisy, just like the one located under the dial. An 8th button located above the wheel is used to change the sensitivity of the sensor on the fly, at the cost of a little digital gymnastics. It does not protrude too much from the mouse shell and is not disturbing in the heat of the action.


The optical sensors are now all more efficient than each other, so that the variations between the latest models are made on very subtle details or in terms of energy saving and surface recognition. The PMW3327 from Pixart that equips the Corsair M55 RGB Pro is no exception to the rule, displaying high-flying characteristics: maximum operating speed at 5.6 m / s, maximum acceleration of 30 g and sensitivity of 6,200 dpi than Corsair double software (for an interest always close to nothing, let us emphasize it once again). 

The sensor cut -off height ( lift-off) is around 3 mm according to our tests, which can be a little high for some players lifting their mouse a lot to center it (game in low sensitivity, typically), but we do not note any abnormal movements of the pointer anyway . Similarly, no acceleration or smoothing to deplore, the accuracy of the sensor is thus of good level.

Question recognition of surfaces, it is also satisfactory. Just avoid too shiny or transparent coatings. In any case, it is strongly recommended to use a mouse pad for video game use, so as to benefit from the best possible precision, to improve gliding and at the same time limit the wear of the skates.


  • Perfectly ambidextrous.
  • Design adapted to a large number of morphologies and grips.


  • Braided USB cable too rigid.
  • The notches of the dial should have been a little firmer for video games.


If the M55 RGB Pro does not surprise with its very classic design, it does not disappoint either and will delight lovers of ambidextrous mice or left-handers who struggle to find mice in their hand. Without excelling, it proves to be sufficiently efficient for the game and not too tiring in daily use. A good little mouse, classic, not perfect, but effective, in short.
