Customer Ratings & Reviews

I got this mouse because I wanted something with some customizable buttons. This works great with the iCUE software and the mouse is definitely on the larger size. If you aren't able to press both shift keys on a full size keyboard with the same hand, you might not like this mouse. The sniper button is forward and can be hard to reach with average hands. Also, the LOD(lift-off distance) is quite high on this mouse and will continue to track. I don't lift my mouse, so it's not an issue, but just be warned it can be an issue.

My EVGA Torx10 was glitching (skipping) so I decided to give this mouse a try since I have several other Corsair RGB equipment for my PC. Got to use that iCUE lol. The Nightsword feels better in my hand (more towards Palm Grip type). The speed and precision to twitch on target seems to be much easier and feels more natural then the Torx10 but not 100% positive because the Torx10 was acting up. The only bad part right now is finding the “thumb” side buttons on the mouse. They are slightly further back and higher than what I would like, I am sure with time I will be able to adjust to it. So right now, I must use “fingertip grip type” when I need to press them.

This is my go to gaming mouse at home. Weighs more than my travel mouse, but very comfy to use for hours.

Fits my had well and super easy to clean I use this for gaming never had a problem!

outstanding! love it! Excellent! will buy it again!

I bought this mouse as an upgrade to a wireless mouse I previously had. It was definitely the right choice. This mouse fits my big hands extremely well. You can plug and play or use the cue software to customize rgb and buttons, including macros.

Great feel in the hand and works great on all fps games I’ve tried with it.

This mouse is great. I have big hands and this mouse fits me well. The thumb shield is great since it helps me avoid rubbing my thumb into my mousepad and serves as a thumb rest. The added weight adjustability is great as well. The mouse is medium weight to start at 4.2 grams, but I have mine set at 4.5 for comfort. It is also right-handed only. The programmable buttons are easy to setup with the Corsair Icue software as well as the RGB lights. It pairs well with the Corsair K70 Mk2 Low profile keyboard I have. The price is also great compared to competitors from Logitech and Razer.

I swapped over from a Logitech G502 and this mouse is fairly comparable as far as feel and performance. Button layout is slightly different and takes some getting used to since the DPI buttons are very close to the left mouse button so you end up adjusting DPI without trying. Back and Forward buttons could be a bit larger or placed lower for better thumb ergonomics. The side button is also way too far forward and should be placed back towards the thumb or made larger. You have to reach to push it. The only feature this mouse doesn't have that my G502 had is the ability to swap the scroll wheel from click mode to smooth. Not a big deal since I prefer the click feel that is standard. Overall I'm pleased with the mouse but for the price, it's certainly not perfect.

amazing form factor for a mouse still hard to beat but I upgraded to the wireless version of this the dark core.

Really like the feel and weight. Great mouse! Lol, its actually my 2nd one. After my first one wore out after 3yrs, had to get another one.

best mouse ever. I work from home and this mouse with its comfort and size is perfect for the amount of work I do from home. I love it

Many macros can be set up, as well as different weight to it for a nice customizable experience. My qualm is it's a bit bulbous for my small fat hands. Making reaching the side "sniper" button a bit of a pain to reach.

I was more than surprised with the quality of this mouse! The ability to add different weight to it was such a huge difference that I didn’t even know I needed. The mouse fits perfectly in my hand so it doesn’t get tired easily when gaming. I have no complaints.

I own a load of Corsair mice (one for each PC/Laptop), keyboards, PC cases, headsets, LED fans and more and I have only been disappointed once, but this mouse is definitely a must-buy. Actually, it feels great, it's highly customizable (the weights, the lighting, the buttons...) and a pure pleasure to use for games as well as everyday tasks. The quality is excellent and the iCUE software a breeze to use. I think the ergonomic shape is what delights me the most as I have rather large hands (and I suffer from early arthritis). Overall, a real winner which I can only recommend.

This mouse is extremely responsive and the customization is crazy. I would recommend this mouse for any gamer.

A great addition to my Corsair keyboard. I love the iCue lighting effects and synchronization. The weight customization is nice too.

As needs change, so do the mice used for those changes. I recently stepped down from a Scimitar to the Nightsword. I love the adjustable weights and the soft grip feel of the device. The fact that I can play with the colors and themes is just bonus

Mouse works great.. very fast and responsive!! Honestly the best I’ve had.

Very comfortable. The option to adjust the weight is perfect.
