The Corsair Nightsword is a comfortable gaming mouse with RGB lighting and an ergonomic design thanks to its slanted shape with a thumb rest. It offers a few programmable buttons, although it isn't on par with a dedicated MMO mouse in that regard. Also, the mouse shows a lot of undershooting and overshooting when it comes to its CPI error, which makes its sensitivity quite unstable. The mouse also isn't recommended for people with small hands, as it's a bit big. On the upside, it's very well-built and has great customization options.

Our Verdict

7.5 Mixed Usage

Good for mixed usage. This mouse can be used at the office or for playing games. It has a few programmable buttons and a wide CPI range. However, people with smaller hands might have to look elsewhere as the mouse is fairly big.

Pros
  • Very low click latency.
  • Very well-built design.
  • Great for palm and claw grips.
Cons
  • Unstable CPI error.
  • Stiff cable.
7.4 Office/Multimedia

Decent for office. It has a comfortable shape and a nice thumb-rest that offers good ergonomics. The mouse is also very well-built, but its cable can get rather annoying and catches on desk supplies easily.

5.2 Travel

This mouse isn't designed for traveling. Its wired design won't be ideal to work in small spaces like on a plane and it won't fit in a laptop bag.

7.7 Video Games (FPS)

Good for video games. It has a wide CPI range and can be customized easily in its software. It's a great mouse for palm or claw grip, but smaller hands might find it too big. Also, the sensor's consistency seems a bit off, and the latency is a bit higher than most wired gaming mice.

8.7 Video Games (MMO)

Very good for MMOs. It offers ten programmable buttons, which isn't as many as dedicated MMO mice. On the upside, its shape is comfortable to hold for a while, but the mouse might be a bit too big for some people with smaller hands.

6.0 Ultra-Light Gaming

Although you can reduce the mouse's weight by removing some weights, it isn't designed for ultra-light gaming. It's a fairly heavy mouse even without its weights in, and there are noticeably lighter options available.

Style

The Corsair Nightsword RGB has a very gaming-oriented design. It's a big mouse that has a lot of buttons and many RGB zones. It has rubber material on the palm and thumb rests, a matte finish on the main click buttons, and a glossy design around the frame.

Like most gaming mice, this mouse isn't the most portable option. It might not fit in most laptop cases, although this won't be an issue for people looking for a gaming mouse for their desk setup.

Design
Build Quality

The Corsair Nightsword's build quality is great. Its overall design feels sturdy and the additional rubber makes it easy to grip. There are no rattling or wobbling parts, but the feet feel standard and glide fairly well. Its heavy weight gives it a hefty feel.

The Corsair Nightsword's ergonomics are good for right-handed people. Its shape is nice and fits nicely with a palm or claw grip. There's also a nice slant to the right, with a comfortable thumb rest on the left side. People with small hands should look for a different mouse, as some buttons might be hard to reach, regardless of the grip you use. This mouse could potentially be used by left-handed people due to its shape, but you might have trouble using the side buttons.

Due to its very long design with a nice back hump, people with small hands might struggle to have nice control over the mouse. It might be a bit hard to reach the sniper button and the forward side button.

Just like with a palm grip, people with small hands might struggle to grab the mouse efficiently and have good control over it. Also, some buttons are harder to reach.

No

No
Fingertip Grip: X.Large Hand
Yes

This mouse isn't designed for a fingertip grip and will be too large for most people. However, very large hands can pull it off, but it won't be as stable as using a claw or palm grip.

The Corsair Nightsword's cable is mediocre. It feels very stiff and has a lot of kinks right out-of-the-box. The cable connection to the mouse also feels oddly long and causes the cable to create even more drag.

The Corsair Nightsword has a very wide CPI range, which you can fine-tune very precisely to suit your preferred sensitivity. Unfortunately, the mouse is extremely inconsistent with our 'CPI Error' test. There's a lot of over and undershooting, which averages to a great CPI error, giving it a better score than what it should. On the upside, the polling rate can be adjusted between 125-250-500-1000Hz and you can adjust both the X and Y axis sensitivity.

The Corsair Nightsword's ten buttons are all programmable, but out of the box, you can easily switch between profiles and CPI settings. There's also a sniper button that can be set to a specific CPI. The buttons all feel solid, although there's a bit of pre-travel on the two buttons situated on the left-click.

Note: The macOS software must be updated to its latest version, otherwise the mouse isn't detected.

Compared to other mice

The Corsair Nightsword RGB is a good gaming mouse that offers a decent amount of buttons, although it does have some CPI inconsistencies and slightly higher latency than most wired gaming mice. See our recommendations for the best gaming mice, the best wireless gaming mice, and the best mice. If you're interested in Corsair products, also check out the best Corsair mice.

Logitech G502 HERO

The Corsair Nightsword RGB and the Logitech G502 HERO are two very similar-looking mice, but the Logitech is better. The Logitech has wheel tilt for more inputs, a more stable sensor when it comes to CPI accuracy, and its lift-off distance is shorter. Other than branding, there's no real reason to get the Corsair over the wired Logitech.

Corsair M65 RGB Elite

The Corsair M65 RGB Elite is a better gaming mouse than the Corsair Nightsword RGB. They have different shapes, but the M65 Elite is better built and fit most grips and hand sizes. Its sensor is also more consistent with its CPI settings. On the other hand, the Nightsword has slightly more buttons.

Corsair IRONCLAW RGB Wireless

The Corsair IRONCLAW RGB Wireless and the Corsair Nightsword RGB are fairly similar, but the IRONCLAW doesn't need a cable to work. The Nightsword is ever so slightly lighter, but both mice have very similar performance.

SteelSeries Rival 600

The Corsair Nightsword RGB and the SteelSeries Rival 600 are fairly similar performing mice, although the Rival 600 has a small edge. It feels more comfortable in-hand and can be used with a fingertip grip. Although its CPI error is higher, it's more consistent, resulting in a more stable control. On the other hand, the Nightsword has 3 more buttons than the Rival 600.

Corsair Scimitar Pro RGB

The Corsair Nightsword RGB is a more versatile mouse, while the Corsair Scimitar Pro RGB is a great MMO mouse. The Scimitar has a 12-button side panel and has an aluminum frame, which feels better built. Its shorter design is better suited than the Nightsword for small hands and its CPI error is more stable, resulting in no big sensitivity swings.
