Corsair has been putting out awesome mouse after awesome mouse, to the delight of casual and hardcore gamers alike. The Nightsword RGB is their latest and greatest, aimed at FPS and MOBA gamers who want a wired mouse with top-of-the-line performance, a slew of programmable buttons, and a highly customizable tunable weight system.

The Nightsword is currently available for $79.99 on Newegg, GameCrate's parent company.

Design and Comfort

From the sharp angles on the mouse buttons, to the massive amounts of textured rubber on the base of the mouse, to the honeycomb filter over the front RGB lighting zone, the Nightsword has a very “gamer” aesthetic. It’s not so gaudy that it’s embarrassing, but I personally prefer a smoother, subtler look to my mice.

When it comes to comfort, the Nightsword hits it out of the park. Plain and simple, I love how this mouse feels. It’s perfectly shaped, with a large, deep curvature that makes the Nightsword fit like a glove. The deep concave grooves on the left and right buttons gently guide your fingers into an optimal position. The textured rubber that takes up practically the entire body of the mouse feels great – it’s just enough of a texture to increase your grip without feeling grating.

The Nightsword also features an attached thumb rest for your right thumb. Even though these thumb rests can “ruin” the aesthetics, from a comfort standpoint, I absolutely love them. This thumb rest also has a little bit of texture to it, similar to the bottom half of the Nightsword’s body. My only complaint is that the Nightsword could stand to be a tad wider – my right ring and pinky finger felt a bit cramped.

The Nightsword has four RGB zones – one in the front, one on the scroll wheel, one on the Corsair logo on the base of the mouse, and on near the rear of the mouse. The front lighting zone is a strange design choice, since you can’t really see it while you’re using the mouse. There’s no denying that the lighting is drop-dead gorgeous, with endless amounts of color choices and patterns available to customize in Corsair’s iCUE software.

Performance and Features

The Nightsword is a premium mouse, so naturally, Corsair has loaded it out with premium components. The 50 million click-rated Omron switches are a joy to use, with a snappy, durable feel, with just the perfect amount of resistance. The PixArt PMW3391 sensor, however, is the real star of the show. This thing is absolutely incredible. Ultra-fast, smooth movements, zero input lag, and an adjustable DPI up to 18,000 – perfect for when you need incredibly precise movements. What’s even cooler is that you can adjust the DPI in single digit increments, allowing for the perfect DPI for whatever game you’re playing.

There are a lot of programmable buttons on the Nightsword – ten in total. The “sniper” button, which by default adjusts DPI as long as the button is pressed and held, is perfectly placed, right underneath my right thumb. The two side buttons, however, are a bit unfortunately placed. They’re a little too high up on the mouse, and hard to distinguish from each other. I had to stretch my thumb to hit them and often hit one when I meant to hit the other. The two top buttons fair a bit better, but I still had a difficult time getting to them – I had to awkwardly bend my index finger. MOBA gamers who live and die by macros will find these buttons essential, but I almost never used them.

The Nightsword’s most exciting feature has to be its tunable weight system. Corsair has included three 2.8 g weights and three 4.5 g weights that you can add inside the mouse. You can weight the mouse in any configuration, from the base weight of 119 g to 141 g with all the weights included. You can position these weights however you’d like in the six different slots, so whether you like more weight toward the bottom of the mouse, or on the left side but not on the right, the choice is yours. There are 120 different weight configurations possible, so there’s a weight setup for everyone. And in a supremely cool move, Corsair’s iCUE software can automatically detect and calibrate itself to your mouse’s unique mass.

The Nightsword RGB is a comfortable mouse with stellar performance that unfortunately bit off a bit more than it can chew when it comes to button placement. If performance is what you’re looking for, the Nightsword RGB has that in spades. Hopefully a future revision will tweak the button placement a bit.
