Buttons, Scroll Wheel

Heading into the land of buttons, the Nightsword's main clickers are really good. They are light, tactile, and nicely spammable. They feel just right and don't feature any significant unnecessary travel (they have a minimal amount of post-travel after actuation, but I'd call it negligible). These buttons have Omron D2FC-F-K switches beneath that are rated for 50 million clicks.


The scroll wheel on the Nightsword is really good. It's very tactile, with well-separated notches, but the scrolling is still pretty light. The encoder is a black TTC one with a supposed height of approximately 7 millimeters.


The middle button is of medium-high tension, which is as expected, but I find it a bit tiring to use in long sessions. I'm used to a lighter middle button, though, so this is just a personal preference of mine. Its travel distance is short, and it uses a small square switch without any branding on it.


The three side buttons (one of which is a "sniper-button") are not the greatest in my book. The two upper ones feel a bit mushy, while the bottom one feels a lot better and is much more tactile. All three have a rather high tension, which I found odd as it makes click-spamming very tiring. These buttons use small, unbranded tactile switches.


The front CPI-buttons are pretty good, but feel a bit mushy. Their overall click-feel is alright, though, and they are light years ahead of the side buttons—these seem to use the same kind of tactile switches.


The profile buttons, which are located beneath the scroll wheel, are generally good; they are tactile and light and can be spammed as well if necessary. They have elevated square switches beneath them.

I also made a video in order to demonstrate how the buttons sound:

Mouse Feet

As far as mouse feet go, Corsair didn't do a terrific job here, and it's so sad that this aspect and the cable are so often overlooked. The feet pretty much have no rounding at their contact edges, which makes them rough, and they generally feel rather scratchy. I don't understand this choice by Corsair since the M65 RGB Elite has some of the best stock feet I ever had the chance to try, but the M55 and the Glaive are also really good examples of this.

Cable

The cable is the second (and, spoiler alert, last) thing I can objectively dislike on this mouse. It's the same story with pretty much all the Corsair mice I have tested before: stiff, heavy, thick, and with a ton of drag resistance. I mean, it surely is very sturdy, but in the world of highly competent wireless and wired mice with cables like on the Glorious Model O and Dream Machines DM1 FPS, it's just a huge setback.

The cable is 1.8 meters long, which should be enough for most users.

Disassembling

I'm not going to lie, I initially very much feared opening this beast up given how complex it looks. Thankfully, it was surprisingly easy as you only have to remove the four main mouse feet (or poke a hole through them) and extract four standard Philips-head screws from beneath before the whole top part can simply be popped off, and it doesn't feature any electronics or wiring at all, which was another surprise. Further breakdown is also easy and intuitive. Huge props to Corsair's engineers for this!
