Customer Ratings & Reviews

Excellent quality and ergonomics. Just feels right.

Love my mouse. Fantastic build quality and great response times.

Love love it can’t find anything that will let me program the sniper button tho

Left double click two weeks past return window. Fantastic! Returned a Logitech for this reason, except that happened within a week of purchase. First of this Corsair mouse had a bad scroll/middle click. Should have listened to myself and just returned and not exchanged. What a waste of $$. Does no one make a reliable mouse that lasts more than a month?!? Sad. Liked this one overall. Back to the old G400S I guess.

The mouse is working fine but weights did not come out inside the mouse. I looked inside the packaging and it wasn't there either. I can't return it because the kids ripped the package apart. This order was a complete disappointment for me.

I have larger than average hands and struggle to find peripherals that are comfortable, this thing is excellent. Fits nicely in my palm. The thumb rest is also nice, contours nicely to my hand. Functionality is very good. Corsair's software isn't the most user friendly experience but not a con for me as I have been using their peripherals for a long time. My previous mouse was the Scimitar, this is a great successor and it so comfortable. As the title suggests, if you have big hands, buy it.

i would have been happier at this price point if it had pinky rest like the left side has for the thumb, and i have to hold my middle finger up in order to avoid clicking the right side button, thats extremely annoying. But it tracks perfectly after months of usage, its still just as responsive, it comes with weights you can install underneath the mouse. from the top of my middle finger to the bottom of my palm is 8" flattened from the side of my hand to my thumbs first knuckle is between 4 and 4 1/2" my hand completely engulfs this mouse both ways, i was looking for something bigger, but this mouse worked the best out of the lot i tried.

So far, pretty happy with this mouse. Switched to this mouse from a Logitech G 502 Hero. Programming buttons in the iCue software is easy, notably easier than in current iteration Logitech G Hub. DPI control is easy and has good starting benchmarks. Side buttons are a little far forward for my thumb compared to the 502 so using the forward side button and the low-DPI button require more effort, but it's not off-putting, just have to build new muscle memory. I miss the ability to unlock the wheel on the 502 BUT I think that feature may have ultimately led to the issues I was having where the wheel didn't always respond accurately after a year of use and that resulted in some upsetting gaming experiences. Thumb rest is comfortable, I realize I had missed having one so that has been pleasant. Overall, happy with this selection even though I've only had it a week.

Excellent gaming mouse. Super responsive, comfortable grip, and the adjustable weights are a great feature. My grandson loves it.”

This mouse was a great upgrade. When I built my PC I recieved a free MSI mouse with my motherboard and after 3 years it was time to upgrade. I never knew what I was missing not having a premium mouse. The buttons are very responsive and the mouse overall feels very solid. It even has a braided cable which I thought was great. The RGB lights are fully customizable and sync perfectly with my Corsair K95 keyboard through the icue software. They even package it with weights that go in the bottom so you can make it heavier or lighter depending on your preference. Two downsides about this mouse. 1) The side buttons feel too far forward. There is no way to adjust this. I have had to adjust my grip on the mouse and has thrown me off a little while getting used to it. After many hours I'm still not used to it. 2) Some of the plastic on the thumb rest is sharp and when I move the mouse I can feel it drag on my mouse pad. Unfortunately I will have to hit it with a file. Not something I should have to do on a mouse that cost $80. 3) Price. This wasnt really an issue for me but could be for some. I use my computer quite a bit (20hrs per week or more sometimes) and looked at it as an investment. Overall I would highly reccomend this mouse. Corsair makes some great stuff and I dont think you will be dissapointed. Even with the few downsides I'm still very happy I purchased this.

Very long time loyal Logitech fan, but my most recent logitech was not doing well and honestly didn't have the typical quality I expected of them. So I shopped around and chose this unit and I'm very happy that I did. I do miss the free spinning mouse wheel but I wouldn't give up the feel of quality and precision I get with this Corsair. The RGB is nice, and the thumb rest I though I wouldn't really need or notice but I ended up loving it. I don't rest my thumb fully on it, just slightly.. but it prevents me from causing drag by being there. Buttons all work smoothly, with a feel of quality and decisive click (not mooshy or too senstive). Love it.

I didn't realize how much I needed a sniper button until I started using this mouse. My last one would cycle through all the dpi's with just one button. This one you can pick 3 different dpi's and a 4th one while you hold down the sniper button. Each one is adjustable in the icue software. You can also customize the rgb effects, different profiles (if you've got multiple users), and the polling rate. I mostly chose a corsair mouse because I already had corsair ram so I wouldn't need to install more software so that was a nice convenience. Icue is generally pretty good, it's a little finicky sometimes with the profiles but I've heard awful things about razer's cloud software. The mouse is pretty comfortable for most hands I'd say. The adjustable weights are really nice. I'm between a palm and claw grip and it works pretty well for me but if you can go into a store and actually hold one, I'd strongly recommend that.

I've been using the CORSAIR - Nightsword RGB Tunable FPS/MOBA Wired Optical Gaming Mouse for a few weeks now, and I'm really impressed with it. It's a great mouse for both FPS and MOBA games, and it's also comfortable to use for long periods of time. One of the things I like most about the Nightsword is its tunable weight system. You can add or remove weights to the mouse to customize its weight and balance, which is great for finding the perfect feel for your gaming style. The Nightsword also has a great sensor. It's an 18,000 DPI optical sensor that's very accurate and responsive. I've been able to make some really precise movements with the mouse, and I haven't had any problems with tracking or jittering. The Nightsword also has a number of other features that I like. It has RGB lighting that you can customize, and it has a comfortable ergonomic design. It also has a number of programmable buttons, which is great for setting up macros and shortcuts. Overall, I'm really happy with the CORSAIR - Nightsword RGB Tunable FPS/MOBA Wired Optical Gaming Mouse. It's a great mouse for both FPS and MOBA games, and it's also comfortable to use for long periods of time. I would definitely recommend it to anyone looking for a new gaming mouse. Here are some of the pros and cons of the CORSAIR - Nightsword RGB Tunable FPS/MOBA Wired Optical Gaming Mouse: Pros: Tunable weight system Accurate and responsive 18,000 DPI optical sensor RGB lighting Comfortable ergonomic design Programmable buttons Cons: Can be a bit expensive Some users have reported problems with the scroll wheel Overall, the CORSAIR - Nightsword RGB Tunable FPS/MOBA Wired Optical Gaming Mouse is a great mouse for both FPS and MOBA games. It's comfortable to use, has a great sensor, and is customizable to fit your needs. If you're looking for a new gaming mouse, I would definitely recommend it.

PROS: - COMFORTABLE!!! - Personalize several weight settings to your liking - RGB (w/ iCUE software) if that's to your liking; works well - Right amount of customizable buttons for most users/ gamers - Build quality is top-notch - Replaces a (functioning) RAZER Deathadder Elite RGB CONS: NONE to date OTHER/ SUMMARY: This replaces my RAZER Deathadder Elite RGB which is an outstanding mouse in it's own right... However, the custom weights, thumb-rest and overall feel (in my experience) does make my gaming experience much better (overall) with the NIGHTSWORD.

Precise pointing, decent rgb thats pretty easy to customise with icue. It also has an easy calibration mode that helped the mouse movement feel more natural in games. The body is wider than my logitech g 50 somthing. The wider body means more of my hand can lay flat on the mouse and no curling my fingers. Adjustable weights are nice too. Its not the lightest but i personally prefer heftier mice so that it doesnt drift at all. Good product for a decent price. If its ever on sale grab it.

Great mouse. Size is larger than others I have used which makes it a much better fit. I don't use the weights because I like it light, but they are neat and snap in and out easily. The thumb button is really useful!

My Corsair Glaive mouse started having issues. They no longer make it so I had to try and find a new one. This mouse is weight tunable RGB tunable as well as DPI tunable. Its a great mouse.

The Corsair Nightsword excellent mouse for grip and comfort and gaming! If you like wired mice this is a mouse for you. I loved my M65 for years and when the time came to replace it I tried other mice. I have large hands and never had many choices in mice, this one fits my grip and no lack of programmable buttons. You can customize this mouse to how you like, add weight or remove. The rubber like grip feels good and the feet glide smooth.

I was looking for a mouse with a cable because sometimes I feel the wireless mouse loses connection so I started looking at gaming mice. This is a really comfortable mouse and I like the lights. Very easy to customize via the app. I like the weights that came with it as well. I was able to balance it the way I like.

What is there to say. It is a very good wired mouse. It has a very long cable that should reach as far as you should need. We put 2 of the weights in the mouse. Feels great in my hand. It has a nice thumb rest on the side. I just love the quality of Corsair.
