The Corsair Nightsword has a great shape to it. I have large hands and it fits nicely. The thumbrest design is great as it prevents your thumb from dragging on the mousepad. The thumbrest is concave in shape allowing you to lift and move the mouse very easily with minimal effort. The rubber on the opposite side where the pinky finger rest also provides a nice grip. The top of the mouse is more of a soft touch plastic with a treaded design for added grip. The left and right click buttons are a matte finish separate from the rest of the body which is nice. The button layout is pretty good for the most part. The DPI Sniper button is reachable but does not sit directly under the thumb which in this case I like so I do not accidentally press it. The Corsair Ironclaw Wireless has larger buttons making them easier to press although the ones on the Nightsword are still good. The scroll wheel feels nice with discernable steps. I really enjoy the fit and feel of this mouse better than the Ironclaw for FPS games. The RGB lighting has a very cool layout on this mouse. It is their best looking mouse. This mouse is very good for FPS games and has all the customizable weights you need. Overall I think Corsair has a winner with this mouse. Can't go wrong with it. Very comfortable and natural feel in the hand. Highly Recommended.

Price: 6.5/10 This is probably one of the most expensive mice I've ever owned. I purchased mine for 95 dollars and had it for a year and a half before accidently spilling tea on it. That's on me though, I loved the mouse so much I bought a new one the same day even though I still had my old Razer mouse on hand. You could pick up the logitech G502 hero which is almost a clone of this mouse for around 50 bucks. At the current price point, this mouse is made for serious gamers/ Corsair enthusiasts like me. It has tons of bells and whistles like weights and macros you can program through Corsair IQ Ease of use: Easily the best mouse I've ever owned. It comes with little weights and automatically detects when you add or remove them. My flicks after I got used to this mouse were insane, I'm talking 20 kills in the first half of a Dust 2 CS match type crazy. The added thumb rest is nice too, its something I never thought I would need in a mouse, but I cant use my pc comfortably without it.

The hardware itself is very good. Wasn’t sure how much the adjustable weight would matter, but I honestly believe that’s what made the mouse for me. It glides perfectly across my desk mat, and all of the buttons are very responsive. Miles better than the mouse it replaced, which turned out to be more villain than hero, if you know what I mean. The software is decent. Takes a second to get used to, but after a while it does fine. I will warn you, if you decide to use the onboard profiling on the mouse, you may get watchdog errors in Win 11 after this last update. I speak from the experience of hours of troubleshooting, system crashes, windows reinstalls, driver reinstalls, etc. in the end, Windows was having problems reading the profile in the mouse (and the Corsair keyboard I have it connected through) and was not happy. Only after reinstalling and keeping iCue running was Windows stable. This is a Windows problem, not a Corsair problem, imo. Just thought I’d add that in here just in case. I lost about 20 hours of uptime because of it. Just run iCue while you’re using the mouse if you don’t want to go insane when MS decides to scramble your system with an update.
