Customer Ratings & Reviews

The feeling of this mouse is great. Awesome colors and even has weights you can add to the inside in order to make it heavier or lighter depending on your style of game play. I also purchased the Corsair keyboard along with this and have no regrets. They both work seamlessly together including the lights through the Icue software.

So far Im loving the weight and the feel of the mouse. I'm also really enjoying the customization of the LEDS with their software.

Great mouse highly recommend. Fits in hand well can add weight inside to help balance the mouse for your gameplay

Fits perfectly and responsive. Excellent gaming mouse and for daily use.

The CORSAIR Nightsword RGB Tunable FPS/MOBA Wired Optical Gaming Mouse in Black is a feature-rich and precise gaming tool that offers a high level of customization and performance. Its ergonomic design, adjustable weights, and advanced sensor make it an excellent choice for gamers seeking to enhance their gaming experience with a reliable and versatile mouse.

Only owned for a short period of time but I love it. I have big hands so it’s comfortable and fits nicely. I game a lot and prefer a heavier mouse (comes with weights). I would say it’s boosted my gaming precision. icue software is a lot to take in but there’s YouTube.

Excellent gaming mouse, I love the adjustability and the ergonomics. A MUST HAVE for anyone, especially those who enjoy Corsair products!

Great mouse. The small details like the thumb rest make a big difference, that i didnt know i needed. The RGB works well with iCue and the ability to add weights to it are nice.

Clean, efficient, customizable, and well-fitted to the hand, this mouse is a great purchase for FPS gaming, but be sure to calibrate it inside the iCue software maybe once every three months to keep it at peak form.

Great mouse I like all the button options. Also has good dpi settings

nice solid feel, buttons are tactilly-nice. dps adjustment buttons are in a bit of an awkard position, but that's good so you don't accidently hit them. Did knock a star off as upon first installation, the middle mouse buttons adjusted the lighting profile on icue, instead of a 'normal' mouse function.

Easy to use. Software takes time to adapt to, but overall great quality.

I've always been fond of heavy mice. I loaded all 6 of the weights and it feels fantastic in my hand! Tracking is great , DPI is adjustable on in the fly. RGB lighting syncs up with my Corsair RAM, keyboard, and headset! Would definitely buy again!

My gaming experience has improved greatly since buying this mouse and the Corsair k68 keyboard. Very responsive and customizable buttons, sensitivity, weight, and colors. Plug and play, and additional software only for changing colors. Very easy to use.

This is hands down my favorite mouse I've used, and I've been through a lot. Multiple Logitechs, a steel series, a few razers. I love the thumb rest and the button placements are all comofortable.

Great, very unique mouse. Really good for a better hand grip if you are battling with Hand syndrome.

Love this mouse. I've been a Corsair fanboy for a long time but if you enjoy gaming but don't like a mouse with TOO many buttons this one is a perfect spot. There's plenty of extra buttons to bind different functions to but not so many that you're accidentally tapping them all the time. The mouse also comes with a set of weights, so if you prefer you mouse with a bit more heft that's also a great asset.

The design of the mouse shape is excellent! It allows my hand to rest comfortably, which is very important to me for long time work. It also has weight adjustment system so you can adjust the best weight as you like. Those programmable buttons definitely gives a better in-game experience, but have to get used to it first since it might be easy to accidentally click the side buttons. Overall great mouse with both look and functions.

I really like this mouse. I got it because less than a year of having a different mouse that is a big name, I started having some left-click issues. This isn't ideal with FPS games and so far this Corsair mouse hasn't failed me. It's fast and I like the big build of it. It's definitely bigger and more robust than my other one. Some may like that, some may not. I would recommend this mouse to others. The buttons by the thumb are also nice. I just wish it had horizontal scrolling. That would really make this mouse top-tier for me because I use the same setup for my work space and use Excel sheets every day. That's the only reason it's not 5 stars for me. But if you never need/use horizontal scrolling, then this mouse is great. Some people like lighter mice and this one has a little bit of weight to it. If you like a little weight/substance, then I think you'd really like this mouse.

I have always been a Logitech G502 fanboy and loved that mouse and it's layout but the software was abyssmal and caused issues with iCue for my system RGB and other apps. I decided to try and convert to Corsair to keep within the same ecosystem and while I was reluctant at first, I am a convert now! Everything about this mouse is better, buttons, light, comfort with one exception: I miss being able to toggle the scroll wheel from fast scroll to click scroll but other than that, this thing is better on every level.
