Corsair M55 RGB Pro Ambidextrous – Design and Features
Aside from its minimal RGB lighting, the M55 RGB Pro doesn’t look much like a gaming mouse. Its shape is fairly standard and might lead you to believe it’s a regular mouse for normal desktop use. There are no aggressive lines or angular accents that would indicate its gaming intentions. Once you grip the mouse, however, you’ll begin to understand it’s meant for the twitchy, sweaty mitts of gamers. It has textured, rubberized side grips that keep your thumb, ring, and pinky fingers firmly anchored in place. The sides are slightly sculpted to create a natural feel for your thumb and fingers. The matte black top piece offers a subtle grit that helps keep your palm and mouse-click fingers from slipping.
Weighing just 86 grams, the M55 RGB Pro is on the light end of the gaming mouse weight spectrum. It weighs the same as the nearly ambidextrous Logitech Prodigy G203 and slightly less than the SteelSeries Rival 310 and Sensei 310, which weigh 88g and 92g respectively. It’s much lighter than the right-handed Corsair M65 Pro RGB, which ranges from 115 to 135.5 grams using its tunable weight system.
Corsair may have skimped on the M55 RGB Pro’s design in order to hit its low price, but it didn’t cut any corners with this wired mouse’s cable. It’s six feet in length and braided – no short, rubbery cable prone to knotting and tangling here.
The M55 RGB Pro has two zones worth of RGB lighting – one for form (Corsair logo) and the other for function (DPI indicator LED). The Corsair logo is the larger of the two zones and can be programmed as a solid color or a color-changing pattern. It’s the only zone that you can program as a pattern, and with only a single zone, most of the patterns you can select in the iCUE software look the same, which is a bit of a bummer. You can also program the DPI indicator light as a different color for each of your DPI settings, a useful tool in knowing the DPI level at which you are currently fragging.
Some mice such as the Logitech Prodigy G203 look ambidextrous with their symmetrical shape but feature only one set of side thumb buttons, which leaves the thumbs of lefties in a lurch. The M55 RGB Pro is truly ambidextrous – it offers a symmetrical shape and a set of buttons on each side. There are eight buttons in all, but only six are activated by default. In right-hand mode, the two thumb buttons on the right side are deactivated, and the reverse holds true in left-hand mode. The other four buttons are located on the top: left- and right-click buttons, a clickable scroll wheel, and a button behind the scroll wheel that lets you cycle through your DPI levels. There is no dedicated sniper button, but you can easily program one of the thumb buttons to act as such using the iCUE software.
The mouse’s optical sensor on the bottom panel is surrounded by three glide pads that create a smooth feel. The sensor itself is PixArt 3327 optical sensor with a 12,400 DPI sensitivity. It was more than I needed for my 32-inch 4K monitor and great for the price. By comparison, the budget Logitech Prodigy G203 has a 8,000 DPI sensor, and the pricier Corsair M65 Pro RGB has a 12,000 DPI sensor. High-end mice that cost roughly double the price of the M55 RGB Pro offer greater sensitivity, including the 16,000 DPI HyperX Pulsefire Surge RGB and the 18,000 DPI Corsair NightSword RGB.
Corsair M55 RGB Pro Ambidextrous – Software
Like other Corsair peripherals, the M55 RGB Pro works with Corsair’s iCUE software. iCUE has a polished look to it and is responsive and easy to use. The software lets you program the five DPI levels you want to be able to cycle through on the mouse, plus the separate sniper setting. There is no dedicated sniper button on the mouse, so I programmed one of the side thumb buttons to act as the sniper button. If five DPI levels is too many, you can disable as many as you like so that you can cycle through only two or three DPI stops, for example.
On the lighting effects page in iCUE, you can set the color for the Corsair logo and DPI indicator LED. For the logo, you can opt for a solid color or a number of effects, but many of the patterns for the effects look the same since the pattern can’t cycle through multiple zones. The single logo can only pulse and change in so many ways. Unlike more high-end mice from Corsair, you cannot perform surface calibration (to help improve tracking and aiming) or enable angle snapping (to help you track in a straight line) in iCUE for the M55 RGB Pro.
You can, however, check a box in Settings in iCUE to enable left-hand mode. And there’s another checkbox that lets you enable all eight buttons – that includes both sets of side buttons at the same time. I would worry more about accidentally pressing the side buttons with my ring or pink fingers, but the option is there if you need all eight. You can also adjust the mouse’s polling rate; it is set at 1000Hz/1ms by default but you can lower it to 500Hz/2ms, 250Hz/3ms or 125Hz/4ms if you want to decrease the drain on your CPU and don’t mind adding a little lag to the equation.
While it is certainly easy to check and uncheck a box in iCUE to toggle between right- and left-hand modes, you can also perform this maneuver on the mouse itself. Just hold down the two side buttons on the left for five seconds to go put the mouse in left-hand mode or the two side buttons on the right for right-hand mode. The mouse’s lights will blink red three times to indicate you have successfully switched modes. This shortcut is handy if you need to switch the mouse and are using a PC without iCUE. (This shortcut doesn’t work, however, on a PC with iCUE installed, even if the software is not running.)
The mouse has onboard storage so you can take a single profile with you when playing on a friend’s PC. You can create and save many more profiles to your PC in iCUE, but you can take only the active profile with you.
Corsair M55 RGB Pro Ambidextrous – Gaming
To test the M55 RGB Pro, I played CS:GO, Fortnite and Overwatch. The mouse glided smoothly, and the 12,400 DPI sensor was more than I needed on a 32-inch 4K display. I was most comfortable at roughly half that figure – 6,000 DPI at the most.
The shape of the mouse is neutral, but I think claw-grippers will feel more comfortable than palm-grippers. The mouse sits fairly low without the hump that palm-grippers require for maximum comfort. The textured rubberized side grips did their job and provided a slip-free grip that stayed secure during long sessions. The side grips are what separate the M55 RGB Pro from ordinary mice (along with its RGB lighting and high-end optical sensor.)
The placement of the side buttons is effective – they stay out of the way when not needed, but didn’t require me to stretch or adjust my grip to engage them. I tried using both the front and back side buttons for sniper mode and found I liked the back button better, but either is suitable since they sit right above your thumb.
Having a preference for heavier mice and just tested and reviewed the Corsair NightSword RGB, the M55 RGB Pro felt a little too light to my mousing sensibilities. This feeling is entirely subjective, of course, but the M55 RGB Pro is definitely a lightweight among gaming mice and lacks a tunable weight system that would allow you to make it heavier.
The Corsair M55 RGB Pro Ambidextrous Multi-Grip Gaming Mouse has an MSRP of $39.99 and it’s usually the same price online.
