Corsair M55 RGB PRO Overview
Once out of its box, the ambidextrous shape of the M55 becomes apparent, with a narrow body, and dual thumb buttons on both the left and right sides of the mouse. There are no extreme, swooping curves found on the M55, though each side panel of the mouse is arced to provide a comfortable thumb grip, no matter what hand you use. The M55 RGB PRO is by no means a large mouse, with a 57.25mm width, 124.4mm length, and 40mm height. The single-piece, upper-body portion of the M55 RGB PRO is a slightly textured black plastic, just like the surfaces found on existing Corsair mice. We really like this texture, as it provides a somewhat grippy surface without being too rough, and has held up very well over time in other Corsair products.
Taking a look down on the M55, we really see the ambidextrous layout of the mouse, with equal curves and appointments on each side. The left and right mouse buttons are part of the single-piece mouse body upper, and have a bit of a convex curve to them, as opposed to a concave surface to guide your fingers to their places. Hidden beneath these buttons are Omron switches with expected lifespans of 50 million clicks.
Nestled between the left and right mouse buttons is a standard mouse wheel with a bit of a honeycomb texture to it. The mouse wheel has a very lightly ridged scrolling motion, as well as a standard click function that can be programmed via Corsair’s iCUE software. Located just behind the wheel is a small RGB LED indicator that serves as a DPI setting indicator. And finally, there is a DPI cycle button right behind the DPI indicator LED that is used to cycle between five DPI settings, which can be adjusted in 100 DPI increments within iCUE.
Towards the rear of the mouse is an RGB LED illuminated Corsair logo, that can have its color and lighting effect adjusted in iCUE to match the rest of your Corsair peripherals, or to have a lighting effect of its own.
Taking a look at the left side of the M55 RGB PRO, we see a pretty basic layout. A large rubber surface is present for keeping your thumb in place, and the triangular texture pattern gives a good amount of grip without being rough and obnoxious. Just above the thumb area are two buttons that by default function as forward and back buttons, but these too can be customized to a variety of functions within iCUE.
The right side of the M55 is a mirror image of the left, as you would expect. Left-handed mouse users can now take full advantage of a mouse designed to provide them the same thumb functionality that right-handed mouse users have been privileged to use for years.
The front of the M55 has a pretty standard layout, with the braided cable exiting from between the left and right mouse buttons. A slightly reinforced rubber sheath exits the body of the mouse and ensures the braided cable has a well-supported connection the the mouse body.
Looking beneath the M55 RGB PRO, we see a quite normal layout. A large PTFE glide pad at the rear of the mouse, along with two smaller pads at the front of the mouse, provide a good balance of durability and agility to the M55. Centered on the base of the mouse is the opening that leads to the PixArt PAW3327 optical sensor, with a DPI range of 200 – 12,400, in 100 DPI steps. Capable of speeds of up to 220 inches per second, and acceleration up to 50G, the PAW3327 provides accurate tracking, even at high speeds and in rapid movements.
At the end of the braided USB cable, is a newly designed USB plug. This smaller body is a welcomed change from some of Corsair’s previous products that had big and bulky USB connections.
