Customer Ratings & Reviews

The dark core mouse is good it's not to heavy and not to light, it feels good in the hand, but they need to make it easier to remap the buttons on the mouse I still haven't got it to work and iv had it for 2 weeks

Love it. Always buying Corsair products any chance I get. Get the wireless charging mouse pad if you get it. Now a fan of the software for programming the buttons.

I really like this mouse. I prefer wired mice but this is probably one of my favorite mice I have which is a few and its wireless.

It was a birthday present for 9-year-old son. He likes the RGB lighting a lot. Naturally, he's not taking advantage of the advanced features, but from my limited use, they work as advertised.

This is a fun gaming mouse. I'm a casual gamer, and the custom profiles with macro recording makes gaming fun. The battery life is decent, but I leave mine plugged in.

The wired or Bluetooth option is nice the cable does not drag or come unplugged very good fit and Finnish

I bought this mouse for gaming and school use. By far the best mouse I’ve EVER used. Pricing was good, the feel is perfect and it’s so quick with the response that there is virtually no lag.

Only giving a 4 star due to the battery not lasting as long as expected. Would looking at an Qi charger in the near future.

It's a nice mouse having rgb is all the rage. I also have the k65 it's really the same just wireless it's a little big .

It’s overall good gaming mouse with RGB, however there is no iCue software for Mac for its Bluetooth / RGB setting. And for Windows it’s light not synchronized with rest of the Corsair pc parts like ram, AIOs, RGB fans etc. another word it’s standalone preset RGB while you can choose which preset you want from iCUE software. Performance wise it’s good average with nice heft to it, and economic shape to my large size hand.

So, I'm not a Corsair user normally, I prefer Logitech, but I needed a good bluetooth mouse that was gonna work (ya know, scroll the direction I'm telling it too...). So I got this mouse... and oh my goodness I'm in love!!! It's got a lot of colors, lots of buttons, the scroll wheel works lol. The battery lasts a long time and it has yet to act up! My only dislike is how short a time it sits inactive before it goes idle. But I'll take that over the problems I had with Logitech!!

The mouse works really well on 2.4ghz and wired. Bluetooth did not work very well. Battery life is not that great.

This is the perfect mouse for my office. I already use a Qi charger for my phone. So at the end of the day, I place my mouse on the charger and come back to work with a fully charged mouse. I also went ahead and programmed the extra buttons to do functions aside from gaming (i.e. return, delete, backspace, left and right arrows). This helps keep me from having to take my hand off the mouse when making simple changes. I also turned off the lights just because I am in the office and not trying to be flashy. I'd highly recommend this mouse to anyone that is tired of changing their batteries.

i was excited when i bought this mouse it seemed like a really quality mouse and it is. But i bought it to play games with primarily. SO it is important that it maintain a constant dpi while you play. This mouse i knew the minute i saw where the dpi selection switch was i was in trouble. So you are in a Tough Boss fight and it switches dpi on you now all of a sudden instead of a quick response mouse you need a 4'x4' desktop just to move you character a few feet. Who puts a dpi button right beside your main attack button and doesn't allow you to lock your dpi selection so you don't inadvertently change it all the time. I installed the software same problem you will accidentally change the dpi no matter what. So i used this mouse about an hour and it has been sitting on a shelf ever since. It is not something you will want to play games with. Which is what i bought it for,was a waste of my money.

Comfortable to the touch, don't like the strafe buttons. A bit to far apart for me liking.

Love the mouse, but not a huge fan of the Corsair software. I like the ability to use it wired or wireless.

Changed from the Elite M65 to the Nightsword and havent found a reason to go back. I love Corsair their products are quality. Least the ones I have.

Too small for big hands! I am 6'2" tall & mouse makes hands ache! Heavy, Poor button placement. bad cable not type c & it broke, connection issues, So bad that it changed my opinion of CORSAIR

The mouse is very responsive. The only thing that would make it great is if the charge was longer.

As the title states, I am torn on this mouse. It is the typical high quality that one expects from Corsair. Wireless/Wired is an awesome choice to have and the RGB is rad. But the battery... oh my the battery. While I realize the qi charging mat is available and it charges while being plugged, the battery life is a joke. I am lucky to get 3 hours of time with a full charge. I don't do much that would kill the battery either other than gaming. And that's the rub: the battery life is atrocious gaming or working. It's so bad that as the only real quibble I have, it almost overshadows the rest of the mouse. I shouldn't have to plug in this mouse for most of the day while I work. I shouldn't have to purchase an outrageously expensive mouse pad to charge the mouse. I came from a Logitech G602... yeah... from 2013. So this has made me want to go back to the endless battery life of that mouse. Almost. If you can get past the battery life, this is an incredible mouse for the money. Lots of options, super portable, great quality and you know it will last a long time. But man... that battery life....
