The Corsair M55 RGB Pro is a good gaming mouse that has an ambidextrous design and two sets of two side buttons. The mouse is rather long and large, which is better suited for people with larger hands. Its performance is good, although the sensor seems to behave differently depending on your mouse movement speed, which results in inconsistent sensitivity. On the upside, its click latency is very low and it's not too heavy if you can eliminate the weight of the wire.
Our Verdict
The Corsair M55 RGB Pro is decent for mixed usage. This mouse is mainly designed for gaming and is surprisingly lightweight if you get rid of the cable's weight. It isn't ideal for office work due to its stiff cable, and wired-only designs aren't great for traveling.
-
Good build quality.
-
Can be used left-handed.
-
Low click-latency.
-
Inconsistent sensitivity.
-
Stiff cable.
This is a decent mouse for the office. Its ergonomics are good unless you prefer right-slanted or left-slanted mice. The mouse is well-built and has a few buttons to make work more fluid, but it has a wire that's stiff and can clutter up your desk.
The Corsair M55 RGB Pro isn't designed as a travel mouse. This gaming mouse is rather bulky and always-wired. It will be hard to fit it in a laptop bag.
Good for video games like FPS. The click latency is very low and feels responsive. The mouse is also fairly lightweight if you can eliminate the cable's weight. The mouse has a symmetrical design with two side buttons on each side, which gives you more inputs. It has a wide CPI range that's customizable, but its sensor consistency seemed a bit off during testing.
The Corsair M55 RGB Pro is good for MMO games. The two sets of side buttons on each side offer extra inputs, but it won't be as great as a dedicated side MMO panel with multiple buttons. On the upside, the mouse feels responsive and well-built, but there are way better MMO options available.
The Corsair M55 RGB Pro is a good mouse for ultra-light gaming, although it's not necessarily designed for that purpose. The mouse is surprisingly light when you eliminate the weight of the cable, but it won't be as light as other mice specifically designed to be the lightest possible. It's a good alternative for people looking for a lightweight standard mouse that doesn't have a honeycomb pattern.

Test Results
The Corsair M55 RGB Pro is a fairly straightforward looking mouse. It has a symmetrical design with two side buttons on each side of the mouse. It also has RGB lighting on the manufacturer logo and can have solid colors set for the CPI settings. There are also rubber grips on both sides of the mouse.
The Corsair M55 isn't too heavy, especially if you use a bungee to get rid of the weight of the cable. However, there's no weight optimization.
Like most wired gaming mice, the Corsair M55 RGB Pro isn't the most portable. It's rather bulky and might be hard to fit in a laptop case, but this won't matter for people who are looking for a gaming mouse for their home setup.
The Corsair M55 RGB Pro is a well-built mouse but isn't quite on par with some other Corsair mice we've reviewed so far. The whole body is made from solid plastic, but the rubber grips feel a bit cheap as they flex under moderate pressure. The clicks from all the buttons are easy to actuate and feel good. However, the increments of the scroll wheel are a bit soft and don't offer precision scrolling.
The ergonomics of this mouse are good. Its long and large body makes it comfortable for a wide variety of hand grips. This design is also fully ambidextrous thanks to the two side buttons on each side of the mouse. You can also invert the left and right-click buttons in the software.
People with small hands might have a bit of difficulty reaching the mouse wheel and the front side buttons.
Just like with a palm grip, the front side buttons and the scroll wheel might be a bit harder to reach for people with smaller hands.
The Corsair M55 RGB Pro's wide back makes it hard for people with small and medium hands to have nice control over the mouse with a fingertip grip.
This mouse is wired-only and can't be used wirelessly.
The Corsair M55 RGB Pro's cable is fairly rigid and keeps a lot of kink from the packaging. It's quite similar to some Razer mice.
The Corsair M55's click latency is very low and most gamers won't notice any delay when playing games. The mouse clicks feel very responsive.
The Corsair M55 RGB Pro's performance is very good. It has a wide CPI range that can be customized inside its software. You can also switch its polling rate between 125-250-500-1000Hz. However, its lift-off distance is noticeably higher than most gaming mice, which is sub-par. Also, the mouse seems to overshoot with slow movement and undershoot with fast movement, which averages out at an excellent CPI error. This isn't ideal for users as the sensitivity changes when using the mouse at different speeds, which is unwanted.
You can easily program each of the Corsair M55's buttons in its software. It has a dedicated CPI switch button on top of the mouse, but you'll have to program a profile switching button in the software if you want it.
The Corsair M55 RGB Pro's scroll wheel has very soft increments, which don't provide the best feedback for precise scrolling.
The Corsair iCUE software allows you to customize the RGB lighting, the performance settings, and save different profiles for the mice. You can also disable either the left or right side buttons, or use all four.
Compared to other mice
The Corsair M55 RGB Pro is a good gaming mouse, but unfortunately, its sensor seems to be a bit inconsistent, making it a worse choice than similar products with a better sensor. On the upside, the mouse is rather lightweight, without having an ultra-light honeycomb pattern. It also has two sets of side buttons, which is great, but might not be enough for MMO players.

The Razer DeathAdder Elite and the Corsair M55 RGB Pro are very similar mice, but the DeathAdder has better overall performance due to the M55's inconsistent sensor sensitivity. The DeathAdder shape and size is also better suited for a wider variety of hand sizes and grips, due to its right-slanted design. Its lift-off distance is also noticeably lower. On the other hand, the M55 will be a better option if you want to use your mouse left-handed, and it has more inputs thanks to two side buttons on each side of the mouse.
The Logitech G203 is better than the Corsair M55 RGB Pro. Its sensor is more accurate and consistent and it feels slightly more durable. However, the G203's low-profile might not be ideal for everyone and will be better suited for smaller hands than the Corsair. The Logitech's cable is also better and doesn't feel as stiff, but the M55 has two sets of two side buttons, while the G203 only has one of its left side.
The Corsair M65 RGB Elite is a better mouse than the Corsair M55 RGB Pro. The M65 is better-built thanks to its aluminum frame, but it's a bit heavier as well. Also, its sensor is more consistent and doesn't seem to undershoot or overshoot depending on the mouse's movement speed. On the other hand, the M55 has two side buttons on each side, giving it a true ambidextrous design, while the M65 only has side buttons on its left side.
The Logitech G502 HERO is slightly better than the Corsair M55 RGB Pro. While its a bit heavier, the G502 features more buttons and also has an unlockable scroll wheel. It's better-built and is also compatible with macOS. However, the Corsair might be a better option if you prefer a more straightforward design.
The Corsair M55 RGB Pro is very different than the Corsair Scimitar Pro RGB. The M55 will be better suited for FPS games while the Scimitar will be better for MMO games thanks to its 12-button side panel. The Scimitar is also noticeably heavier but feels better-built thanks to its aluminum body.
