Customer Ratings & Reviews

Corsair is one of my best gaming peripherals brand; I have been using their products for many years and have never been disappointed with their quality and performance. The NIGHTSWORD v2 WIRELESS SD is no doubt an excellent device that is packed with features that make it stand out in terms of performance and comfort. Before I dive into the details, but one of the features that liked most is the integrated Elgato Stream Deck functionality. Since I already use a Corsair Galleon 100 SD keyboard with integrated Stream Deck functionality, so having the same features also in mouse I kind of liked the idea as it provides an easy access to my custom shortcuts, applications, and controls. Inside the box, Corsair includes the NIGHTSWORD v2 mouse, a 2.4GHz SLIPSTREAM Wireless USB receiver/dongle, a USB adapter, and a USB-C to USB-A charging/data cable. After completing the unboxing, I plugged in the 2.4GHz USB dongle into my PC and launched the Corsair Web Hub to customize the mouse and check for any available firmware updates. I tend to like using Corsair Web Hub over the iCUE software because the software can sometimes glitch, so having a browser-based option is an awesome alternative. After spending several hours using the Corsair NIGHTSWORD v2, I can genuinely say that it is one of the most comfortable gaming mice I have ever used. Despite its lightweight, it still feels solid and well-built in my hand. Although it is noticeably lightweight but does not feel cheap. The ergonomic design makes it super comfy in hand. The shape fits naturally in my hand, and the dedicated thumb rest provides more comfort to my hand and gives me better control. When it comes to performance, this NIGHTSWORD v2 really shines. And comes packed with modern features for gaming. It features up to 33,000 DPI, 750 IPS tracking, and 50G acceleration. I found it very great not only in gaming but also for productivity. The 8,000Hz hyper-polling is another impressive feature. Having 8K polling available in both connection modes either wired or 2.4GHz wireless, which is incredible that I experience no lag whatever. The RGB lighting looks fantastic and that is also customizable. Personally, the dedicated Elgato Stream Deck Launch Button is the star of the show here. With a single press, I can bring up the Elgato Virtual Stream Deck and access all of my custom shortcuts, applications, controls without a need to have another device. One mouse can do all of that. Overall, I am very happy with it for all what it offers, reliable performance and comfort.

GOOD - Very comfortable and ergonomic - Plenty of programmable buttons - Wired, wireless USB, and Bluetooth connectivity - Simple web-based programming - Steam Deck integration has a lot of potential for games and productivity BAD - Steep learning curve for anyone who doesn't already use Stream Deck - Can't relocate the Stream Deck or profile switch to other buttons on mouse - Rather expensive TLDR Unless you already use Stream Deck for a lot of functions in your daily computing use, the new Nightsword is simply too expensive and too niche for a lot of consumers. The web programming is OS agnostic, which is nice because you can use it on nearly any OS ( even a Chromebook ) and the mouse stores the customization on-board. But making changes is slow and you can't relocate the functions for the Stream Deck or mouse profile switch to any other button on the mouse. You might be better off getting a normal physical Stream Deck pad for $60 - $80 rather than a Nightsword. DETAILS I find many gaming mice to also be excellent for productivity use. Having lots of buttons readily available that can be mapped to common keystrokes like Ctrl+C/Ctrl+V, PgUp/PgDn, and more are great for getting serious work done. Then you can switch between productivity button maps and gaming profiles when you need to. The prospect of Steam Deck integration, with it's virtual macro controls, is very promising. However total execution on the Nightwsord v2 is lacking. First, the good. I found the mouse quite comfortable to hold and use. I tend to rest my palm on the mouse, and doing so my thumb tip came right up to the edge of the three thumb buttons. All the buttons are in quick and easy reach. The box claims 9 customizable buttons, which is technically correct, but that includes the forward and back navigation buttons and the scroll wheel tilt, and I doubt most people will change those from their standard use. So really think of it as having four additional customizable buttons. I could stand for the mouse to be a little heavier overall, and it felt a tad back-heavy ( when I pinch my thumb and ring finger to pick up the mouse, it tilted backward ). But that's mostly personal preference and not something that's a given for everyone. The mouse has three ways to operate, using wired USB, wireless USB dongle, and Bluetooth. A switch on the bottom switches the mode of operation. Since the mouse stores its customization profiles on-board, that means it's easy to use between multiple devices and retain the button maps you set up. To customize the mouse, you must use Corsair's special webpage application. Again, bonus points for flexibility in that it will work on Windows, Mac, Linux, and even a Chromebook ( though it only works with Chrome, Edge, and Opera browsers ). However, the downside of the web programming is it can be quite slow. Since everything has to be stored on the mouse itself, the web app has to save all changes to the mouse when they're made. Meaning you can't make a new profile with all the different lighting and button assignments you want and then save those changes in one go. If you remap a button, the changes have to be saved immediately. Change another button, another 5-10 seconds of saving those changes to the mouse. If you make a lot of profiles, it can take quite a while. As for the Steam Deck integration, that's a large can-o-worms and a very mixed bag. I've been using different kinds of custom and programmable keys and input for my games and productivity for a while. First thing you need to know is training yourself to use additional keyboards, game pads, and button thingies to do tasks can be a very steep learning curve. Sometimes it takes weeks of daily use before those new movements become natural habits like typing on a regular keyboard. While you can reprogram all the Nightsword buttons to interact with the Stream Deck desktop application, you're unlikely to do that since you still need most of the regular mouse buttons for whatever you're doing. You'll probably end up mapping a few buttons directly to the Stream Deck app, or more likely, use the Virtual Stream Deck overlay on-screen. However, using this virtual on-screen keyboard doesn't always play nicely with games and other full-screen applications. If the Stream Deck button could be used as some sort of function shift key, something that would temporarily shift the mouse mapping profile allowing you to map other functions to button chords, that would be much more handy. However, the Web Hub software won't let you change the location or behavior of the Stream Deck function ( or the Profile Switch function, which allows you to cycle to the next button map profile ). The functions simply don't show up anywhere in Web Hub as an option to assign to a button. What's more, if you do map either of those buttons to something else, Web Hub can't change them back unless you reset all button assignments to default ( thankfully you only have to reset button mapping, not lighting and every other mouse configuration ). In the end, I simply see this mouse as a little too gimmicky to justify its $130 price tag ( as of this writing ). Someone who's already heavily invested in Virtual Stream Deck layouts for their photo and video editing will probably find some good use in it. But given as you can get 6- and 8-button Stream Deck keyboards for under $80, I think most people that want to add Stream Deck controls to their daily work will probably be better served with one of them. And plenty of Corsair's existing keyboards are supported with Virtual Stream Deck to the same effect without buying a new mouse. For me, my Corsair Scimitar and its 12 thumb buttons still rules supreme on my desktop.
