Corsair NIGHTSABRE WIRELESS Mouse Review

The Corsair NIGHTSABRE has a matte black plastic body with metal and faux carbon fiber accents. There are twelve customizable RGB zones, including two on the front, one on the logo in the palm rest, six in the glossy accent area below the left- and right-click buttons, and three zones around the bottom rear end.

This mouse has good portability overall. While it's somewhat bulky, it's fairly narrow, and there's a compartment on the bottom of the mouse for storing the wireless USB receiver.

This mouse has impressive overall build quality. Its body is made of solid matte plastic, and both side panels and left- and right-click buttons have a textured surface for added grip. A metal bracket piece surrounds the topmost foot on the bottom and then wraps around the USB-C charging port on the front of the mouse.

There aren't any wobbling or loose parts, but there's some minor side-to-side play in the left- and right-click buttons. There's also some minor wobble in the scroll wheel, but that's fairly typical for a mouse with scroll tilt inputs.

Unfortunately, there's considerable flexibility on the left side, and if you press hard enough, you can actuate a side button through the panel. This isn't an issue when using the mouse normally, but it may be problematic if you grip your mouse tightly while gaming. You can see a video of the flexibility on the sides here.

This mouse is somewhat heavy. The weight is fairly standard compared to similar mice designed for playing games in multiple genres, but it's significantly heavier than most mice designed specifically for playing FPS or other fast-paced games.

The Lowest Weight result is obtained with the plastic plate covering the receiver compartment on the bottom of the mouse removed.

This medium-sized mouse has a fairly long symmetrical shape that narrows toward the middle and has a wider backside. It's best suited for medium-sized hands but is also comfortable if you have large hands and use a palm or claw grip. That said, if you have extra-large hands, the mouse may feel unwieldy due to the narrow grip width. If you have small or extra-small hands, you will have difficulty reaching the front side button and the pair of buttons on the outside edge of the left-click button.

This mouse has an advertised wireless battery life of up to 65 hours of continuous use when connected with its USB receiver or up to 100 hours using a Bluetooth connection. The battery life is indicated on the multipurpose LED indicator on the top of the mouse. The various LED codes are listed in the quick start guide. You can see a digital version of this quick guide on Corsair's website here.

This mouse includes a braided charging cable. The cable has mediocre flexibility and retains kinks from its packaging, but it glides smoothly across desks without snagging.

This mouse has excellent feet that glide very smoothly on mousepads and desks. The feet have some sharp edges, which can dig into softer mousepads, but overall, there's only a slight scratchiness when moving across surfaces. If you press down on the mouse as you move it, there's a minor dragging sensation, but this disappears when holding the mouse lightly in your hand.

You can program any button except for the left-click button. The left-and right-click buttons use optical switches, but Corsair doesn't specifically name a make or model of switch used.

The Corsair NIGHTSABRE has remarkably low click latency. It delivers an extremely responsive-feeling experience for gaming in all genres and is well-suited for casual or competitive play. However, due to the unusual implementation of 2000Hz polling, the click latency is somewhat less consistent than most other mice with a 2000Hz polling rate. For more details about polling rate performance, see the Sensor Latency section below.

This mouse has a 'Button Response Optimization' setting in the customization software that Corsair describes as a 'calibration tool for click sensitivity.' This setting appears to add a small degree of switch debounce, which can be helpful to prevent unwanted slam clicks from being registered if you often lift and reset your mouse while gaming. In our tests with other recent Corsair models, we've tested with this setting on and off and consistently achieved better latency results with the setting off. Testing with this mouse was performed with the Button Response Optimization setting disabled.

The Corsair NIGHTSABRE offers outstanding CPI performance. Its sensor delivers exceptional tracking accuracy, and the physical movements you make with your mouse translate extremely close to your cursor movements on-screen.

The Corsair NIGHTSABRE delivers superb sensor latency. The sensor reacts exceptionally quickly when you move your mouse, and these movements very closely match the timing of the cursor movements you see on-screen. We tested this mouse at its maximum advertised polling rate of 2000Hz.

Note: This mouse, and several other recent Corsair releases, operates differently at its 2000Hz setting compared to most other mice from other manufacturers with 2000Hz polling rate options. At its 2000Hz setting, the Corsair NIGHTSABRE sends two reports to your computer at 1 millisecond intervals, whereas most other mice we've tested with a 2000Hz polling rate send one report every 0.5 milliseconds. While the sensor latency performance is still superb overall, it's measurably less consistent than most other 2000Hz options from other manufacturers.

The available polling rate options are 125Hz, 250Hz, 500Hz, 1000Hz, and 2000Hz. An LED indicator between the two profile-switching buttons displays your current CPI setting. Using the customization software, you can change the polling rate, set custom CPI settings, configure the lift-off distance, and perform surface calibration for your desk or mousepad.

This mouse has a rubberized scroll wheel with a textured surface for added grip. Scrolling is quiet and feels precise, and the definition between steps is noticeable but fairly subdued. Pressing the middle mouse button or using the left/right tilt buttons has a satisfying tactile feel and doesn't feel too light or heavy.

The noise made by all inputs is fairly quiet and unlikely to bother those around you.

This mouse uses Corsair's iCUE software, which is reasonably well laid out and straightforward. It allows you to customize a range of expected settings, including CPI, polling rate, RGB lighting effects, and surface calibration.

That said, some options, like macro programming and button assignment, are somewhat less intuitive to use compared to similar software from other major manufacturers.

Additionally, much like similar software options from other major manufacturers, this software is the source of criticism from the broader community. While we didn't experience any issues during the testing of this mouse, many users online criticize this software for requiring frequent updates and taking up disproportionate system resources, among other complaints. This software may be frustrating if you prefer more lightweight software options or no software at all.

This mouse is fully compatible with Windows, macOS, and Linux, but the software is only compatible with Windows.
