Corsair Sabre V2 Pro Ultralight: Does this 36-gram mouse live up to the hype?

The first thing you notice about the Corsair Sabre V2 Pro Ultralight is how unbelievably light it feels. At just 36 grams, it’s almost disorienting the first time you pick it up, like holding air. I remember taking it out of the box and thinking, there’s no way something this light can actually feel good to use. I’m used to a 110-gram mouse, something that feels sturdy and solid in hand. The Sabre felt like the exact opposite of that.

But here’s the thing: that initial disbelief slowly turned into appreciation. Two weeks in, this little mouse had completely changed how I think about gaming peripherals. There’s a certain magic in how effortlessly it glides, how accurately it tracks, and how quietly it gets the job done without showing off.

What struck me most wasn’t the lack of RGB lights or flashy design – it was the precision and comfort hidden underneath that unassuming matte shell. Corsair didn’t make this mouse to look cool on a desk setup; they made it to perform. And once I got used to it, it genuinely felt like one of the best gaming mice I’ve ever used.

Out of the box

When you open the box, you’re greeted with just the essentials. No extra bells and whistles – just a USB Type-C cable, a 2.4 GHz wireless dongle, a pair of grip stickers, and replacement feet. That’s it.

At first glance, it felt underwhelming. But that minimalist approach makes sense once you hold it. The Sabre V2 Pro weighs just 36 grams – so light that it almost feels unreal if you’re used to heavier mice. I normally use a 110-gram mouse, so switching to this had me learning how to aim all over again. My first few rounds of Valorant were rough. My flicks were overshooting, and I was missing easy shots. But after a few games, something clicked. My hand adapted, the movements started flowing naturally, and suddenly the Sabre felt like an extension of my arm.

Features and Specs

The Corsair Sabre V2 Pro Ultralight might look plain, but what’s inside is what really counts.
It packs Corsair’s Marksman S optical sensor, capable of going up to 33,000 DPI, though realistically I kept it at 800 like most FPS players.

The polling rate can go as high as 8,000 Hz, but I tested it at 1,000 Hz – the standard sweet spot for stable wireless performance. The results were impressive. The tracking graphs were smooth and consistent, showing almost no jitter or acceleration, and the polling rate stayed rock-solid throughout my tests.

Weight (Grams)	36
Connectivity	Wired and 2.4 Wireless
Sensor Type	Optical
Switch Type	Tactile mechanical
DPI	Upto 33,000
Polling Rate	Upto 8000 Hz
Tracking Speed	750 IPS
Acceleration	80G
Cable	Braided USB type A to type C
Accessories	A pair of Grip stickers, extra skates

Instead of optical switches, Corsair has gone with custom tactile mechanical switches here, which is a small trade-off to achieve its ultralight weight. They feel crisp, snappy, and good enough to click – no mushiness, no lag. Plus, mechanical switches consume less power, which means a longer battery life.

The included grip stickers add just the right amount of control if you prefer a firmer hold. The mouse connects either wirelessly over 2.4 GHz or via USB-C cable, and that duality makes it extremely convenient.

Performance

Once I got past the initial adjustment phase, the Sabre V2 Pro completely changed how I played. It’s built for FPS gaming, and it shows. The tracking is flawless, the motion feels organic, and the weight makes it effortless to move quickly and precisely.

Each dot represents a data update tied to the mouse’s polling rate, meaning a 1,000 Hz mouse should record one update every millisecond.

I tested it primarily in Valorant, and after just a few rounds, my aim consistency improved noticeably. Every flick felt smoother, and there was a certain level of comfort that’s hard to describe. It was as if the mouse could anticipate my every move, responding the instant I even thought about flicking.

I also tried it in Red Dead Redemption 2 just to see how it handled slower, more cinematic gameplay. It was fine, but the Sabre really shines in competitive shooters. That’s its natural habitat.

The Corsair Marksman S sensor is genuinely one of the best I’ve used. The tracking graph captures how the mouse accelerates and slows down during a quick flick, with the curve peaking at the point of maximum speed. The tightly packed dots along the curve show that the sensor tracked the movement smoothly and consistently throughout the motion. It’s consistent, responsive, and precise. Exactly what you want when milliseconds matter.

Corsair Sabre V2 Pro Ultralight Battery

The battery life on this thing is honestly impressive. Corsair claims around 70 hours at 1 kHz, and that’s pretty much what I got. Even after long gaming sessions and daily use, I rarely found myself worrying about plugging it in.

And when it does run low, you don’t have to stop playing, just plug in the USB-C cable, and it instantly switches to wired mode without any lag. It’s one of those little conveniences that make a big difference.

Software and Customisation

Now, this is where things start to feel a bit limited. The Corsair Sabre V2 Pro Ultralight technically supports Corsair’s iCUE software, but here’s the catch, it doesn’t show up on the desktop app. The mouse is only recognised on the web hub of iCUE, which means if you want to tweak your DPI settings, remap buttons, or check battery levels, you’ll need to do it through a browser.

That’s not the end of the world, but it’s definitely not ideal. Having to open a webpage every time you want to make a small adjustment feels clunky, especially when Corsair’s desktop app is known for offering deeper control and smoother integration across their products.

Another thing that bugged me was the lack of dedicated DPI buttons. Coming from a Razer DeathAdder V2X, I really missed being able to switch sensitivity on the fly. With the Sabre, you’re stuck with whatever DPI levels you’ve pre-set, and if you want to change them, you have to jump into the iCUE web interface.

For a mouse that’s clearly built for competitive gaming, I wish Corsair had included at least one DPI switcher or allowed better on-device adjustment. It’s a small thing, but when you’re deep in a game and need a quick sensitivity tweak, it makes a noticeable difference.

What’s Missing in the Corsair Sabre V2 Pro Ultralight

Now, it’s not perfect. For a ₹10,499 mouse, I did expect a bit more versatility. There’s no Bluetooth, which feels like a miss in this price range. You can’t just quickly pair it to a laptop or tablet without the dongle. So, if you are someone who uses your gaming mouse for work as well, it is a hassle to use on the go while travelling.

There’s also no RGB lighting or flashy design elements, which might put off some people who like their setups to pop. Personally, I didn’t miss it – the matte finish and subtle look actually grew on me – but it’s definitely not a mouse that’ll turn heads visually.

Then again, that’s not what Corsair is going for here. This isn’t a “showpiece” mouse; it’s a tool for competitive performance. Every design decision reflects that focus.

Verdict – Corsair Sabre V2 Pro Ultralight

After two weeks, I can say with confidence that the Corsair Sabre V2 Pro Ultralight absolutely lives up to the hype – just not in the flashy way some expect. It’s not about RGB or extra buttons or fancy marketing. It’s about performance, precision, and comfort and it nails all three.

Once you adapt to its featherweight design, it’s hard to go back. The consistent tracking, crisp clicks, and strong battery life make it a joy to use for long sessions. Sure, it should’ve had Bluetooth and maybe a hint of flair, but those are small sacrifices for a mouse that performs this well.

For FPS gamers or anyone who values raw performance, pure control and responsiveness, the Sabre V2 Pro Ultralight is exactly what its name promises – ultralight, ultra-precise, and ultra-reliable.
