Customer Ratings & Reviews

Speed, precision, and battery-life are excellent characteristics this mouse has.

If the mouse didn't keep having major issues it would be 5 stars, but I have had two replacements and now the mouse wheel on my third does not work and is driving me crazy. I disassembled the mouse to try and clean it and it still does not work properly. I have been a big fan of Corsair products for along time, but in this case save your money and buy something else.

Like that it fits my bigger hand well, the buttons work well and the action is smooth. If I had ato nitpick is why does everything have to have RGB rotating lighting nowadays?

It has easy buttons to help you control better,love how it lights up.

Great mouse for people with big hands. My only complaint. And it’s more on me than the mouse is I was constantly pressing in the right button on accident as it is a bit more sensitive than my previous mouse.

I love this mouse the battery lasts forever and it’s rechargeable

It's very slick and responsive and helps me during a clutch situation

Great mouse! Smooth and no lag. Definitely recommend.

great mouse for gaming and for those who like a bigger mouse

Great material and the best comfort to take the time to learning

This mouse is way better than any of the razor mouses I've had but I'm starting to have some issues with it I can't get it to connect wirelessly only to Bluetooth after resetting the mouse but it still works wired also it's starting to squeak a little with the left click randomly.

It’s neat looking, feels good in the hand, and the battery seems to last a while.

Great weight, accuracy and battery life. All around a really solid mouse

good and well built mouse with vibrant rgb and good feel in the hand

Best mouse I've ever had personally. Love the wireless charging!

It is a good mouse and i really like it. I reccomend.

This mouse is fast and I hate wired so that's good. The only things that are bad about this mouse are the buttom mapping is wonky be prepared to remap them several times and also the dpi randomly changes each time I turn on my pc which firces me to change my sensitivity mid game which is annoying. Other then that the mouse is great.

Best mouse for large hands. Has wings for nonessential fingers.

SETUP Windows set-up and driver installation went without issue. The Corsair Dark Core mouse can be connected to your computer via the included 2.4GHz wireless receiver or via Bluetooth, should your PC be equipped. I found that the mouse worked just fine via Bluetooth, however, for the best performance and control, the included wireless receiver is a better option. Still, the ability to easily move the mouse between computers with a simple Bluetooth connection is extremely nice. USE One thing is for certain, Corsair definitely believes that the more RGB LED’s, the more better (yes, I know, that is a technical term). Any place that doesn’t have a sensor, circuit board, or structural component, gets a splash of LED. There are so many LED’s representing so many different functions and settings, I find them all quite confusing as to which means what. The Dark Core mouse has a very nice heft to it. I prefer a weighty mouse, and the Corsair is reminiscent of my old Logitech MX1100. That is a good thing. It is heavier than all my current Razer, Logitech, and Roccat mice. This is a larger mouse, but still fits very comfortably in the hand. It may very well be the best feeling and fitting mouse I have. One thing that I was unsure of after unboxing was the small “wing” that protrudes out from the bottom of the mouse. Upon initial inspection, I thought this would be annoying and distracting. Once I began using the mouse, I realized I was wrong. Why more manufacturers don’t include this “wing” is surprising. It is a perfect resting spot for your thumb and keeps it from dragging the mousepad during use. An outstanding feature!!! To get the best user experience from the Corsair Dark Core, you must download the Corsair iCue software. While I have other Corsair products, none of them are currently compatible with the iCue software, so upon installation, I received the support needed only for the mouse. Even then, the software consumes a hefty 627MB of hard disk space and requires approximately 2% of my CPU resources. Corsair states that software can take up nearly one full GB of space, if you have other products of theirs compatible with the iCue software. That’s a fairly high burden on the overall system. However, the software does unlock a plethora of features on the mouse. The multitude of buttons are fully programmable, the sensor resolution, report rate, LED light show, it is all configurable and programmable. FINAL THOUGHTS This is one of the more attractive mice on the market today. The LED light show is unique (but quite frankly, gimmicky). However, my son was instantly impressed when he saw it, saying it was the coolest mouse he had seen. Those fancy LED light shows take a toll on battery life, though. It consumes far more power than my Logitech, Razer, Microsoft, and Roccat mice. Thankfully, Corsair uses a standard USB-C port for charging and not some proprietary shaped micro USB cable that the others do. The mouse also charges wirelessly via Qi. A great feature, and something that should be considered a necessity for marathon work or gaming sessions. The iCue software was a bit of disappointment. While it does allow the mouse to be programmed, it doesn’t allow the granular control that the other manufacturers’ software does. Others allow you to adjust the LED light intensity, speed, sensor sensitivity, etc., at a range from 0 – 100 or anywhere in between. The iCue software doesn’t provide this amount of finite adjustment. Aside from the sensor resolution, it really only offers off, medium, and full. A lot can be learned from Logitech’s G-Hub software and its ability to make minute adjustments to the mouse’s feature set. So, should you buy this mouse or a competitors’ product? I feel it boils down to how heavily invested in the Corsair infrastructure you are. If you currently use the iCue software to control other devices and RGB components in your system, then this mouse would be a good choice. Corsair produces quality products and this mouse is no exception. It offers a ton of great features and customization. It allows you to add another component to your PC without needing separate software to control it. The iCue software can control it all. That is a huge plus. Add to that the ability to sync the light show to all your devices and it definitely has that “Wow” factor. However, should you not be heavily invested in Corsair products, I think you would be better served elsewhere. The Logitech G-Hub software offers more granular customization of its products, but unfortunately, those products are limited to accessories like mouse and keyboards and not full system integration like Corsair (mice, keyboards, AiO’s, case fans, memory, etc). Nor does the Corsair Dark Core mouse have that super silky premium feel that the Roccat mice have.

IT IS GOOD, BUT ITS EXTRA BUTTONS ARE A NIGHTMARE, I CANT PROGRAM THEM LIKE "MOUSE BUTTON" INSTEAD, THEY APPEAR LIKE "NUMBER 1, NUMBER 2...." OF THE KEYBOARD, SO I REALLY DON'T HAVE ANY EXTRA BUTTON TO USE IN THIS MOUSE.
