Customer Ratings & Reviews

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

Been a long time Razer keyboard/mouse user for years but their quality has been sinking. Switched over to this mouse from my Razer DeathAdder mice (have gone through a few), and couldn't be happier. The ergonomic shape, thumb rest, quick profile change buttons, customizable RGB and customizable weight, make this a great buy. The sniper mode thumb button is kind of gimmicky, but it works if you have the reflexes for it. Not sure if Corsair was the first to use this mouse shape, but others seem to be following the trend.

Very customizable dpi performance. Smooth control and comfort. I m happy with the mouse. Highly recommended! You can adjust rgb through icue software and update firmware.

TLDR: Great RGB, good for large hands, heavier mouse weight good for low-DPS play. Overall, this is an awesome gaming mouse. Really like the customization of RGB integration through iCue. The weights that come with the mouse make it possible to tune the way the mouse feels in your hands - similar to loading a car with weight on one side or the other to fix curb weight for taking turns better. I will say this mouse is on the heavier side. Even without the weights installed, this mouse is the heaviest I have ever used. If you normally play at lower DPS (like me) and hence use less of your wrist, this may not matter. But if you are trying to play at higher DPS like pro-gamers, I wouldn't recommend this mouse for that style of play. The only issue I have with this mouse is the buttons and overall orientation is designed for larger hands in my opinion. I have smaller than average hands and play with a palm grip. In order to center my thumb on the "sniper" button, I either have to rotate my palm sideways on the mouse so my thumb can reach it better or I have to switch to fingertip grip. I would recommend feeling this mouse in your hand at your local Best Buy's displays before just purchasing sight unseen (which was my mistake).

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

Idk how I’d play the games I do without this mouse. I love the custom weight, the comfort, and all the buttons. The RGB is gorgeous and the buttons are very satisfying presses. Idk if all of them are this way, but my right click is a little soft and found myself misclicking it a lot when I first got the mouse. Now that I’m used to it though it doesn’t happen much. High pricepoint but I don’t regret it. Programming the buttons takes a little time.

My boyfriend plays league of legends and didn’t have a great mouse. He’s been using this one for 2 months and he said he likes it and the clicking is much easier and it’s improved his gaming experience and skill. We were in the store and testing out all of the other mouses and this one was the most comfortable to hold and move around and had the best thumb rest. I think the extra buttons you can program are really cool. We did a lot of comparisons and research before buying. I highly recommend this mouse.

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

This mouse has a couple different settings to it to adjust how fast the mouse cursor moves. I would recommend! It has helped me for a first time pc user (for gaming)

Nice gaming mouse, high quality, rgb in just the right places. Alot of options for how the colors can be set. Ease of use and the speed buttons are nicely located.

Responseive, nice ergonomics, led lighting and control via Ique top notch. Button placment feels intuitive, custom weights alllow users to "tune" to their preferred feel. Good build quality.

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

Quality Mouse, fun RGB, nice weighted feel. The cord is nice and sturdy and has plenty of length for your setup.

Nice grip, sturdy, bright RGBs, ergonomic fitting. Different weights to help stabilize

Great mouse to use for Gaming or everyday use. Like how you can be able to change it to any color or change into the mode that you want it to be for a specific game.

The Corsair Nightsword is everything I thought it would be. Great feel and adjustable weight. Responsiveness is good too. Definitely recommend!

Excellent quality perfect size ease of install happy with it

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

Great mouse. This is the second one I've bought it last 5 years. Got a new PC and wanted to same mouse and kept previous one for my older PC. Great for gaming and everyday PC use. The backlights RGB are cool too. I haven't ever had any issues with this mouse.

I love the way this mouse feels in my hand and the heavier feel it has. This is my 2nd one and the same problem is reoccurring. When i lift and put the mouse down [ kind of heavily ill admit] it will activate shoot button ( right click)
