Meet Maggie, PCMag'sFor some years now, mouse weight—specifically, reducing it—has become a crucial arena in the battle for the title of best gaming mouse. I've seen models with skeletal bodies or holes punched out of the shell to trim fractions of an ounce from the equation. For most brands, about 1.7 ounces would be enough to qualify a mouse as extra-lightweight, but the Corsair Sabre V2 Pro Ultralight ($99.99) lives up to the name: It weighs just 1.27 ounces without sacrificing performance or affordability, making it the lightest gaming mouse I’ve ever tested. Esports pros looking specifically for a feathery, quick flicker will be pleased; our favorite deluxe esports model, Razer's Basilisk V3 Pro 35K, weighs more than three times as much. This model earns an Editors' Choice award of its own as a compelling, value-packed, and hyper-light esports mouse for under $100.
The Sabre V2 Pro Ultralight isn’t much to look at, with its black shell and mostly unadorned design. The two main buttons and the scroll wheel are joined by a pair of additional buttons on the left side of the mouse for righties to tap with a thumb. The hollow scroll wheel in the center offers only basic forward/back rolling movement, with no lateral scrolling.
The shell is a bit slick, but the mouse comes packaged with handy, pre-cut grip tape for the left and right buttons, as well as for both sides. This cheap-but-effective solution may not be for everyone, but I wish more gaming mice included this extra.
What this mouse lacks in aesthetics or bling, it more than makes up for in performance. Built around Corsair’s proprietary 33K DPI Marksman S sensor, it can deliver up to an 8K polling rate.
While plenty of gaming mice can serve up excellent tracking performance, their larger sensors, batteries, and other components can make some models weigh upward of a quarter pound. The extra weight isn’t necessarily bad, but a lighter mouse makes it much easier to land those flick shots in reflex shooters like Valorant, Call of Duty, or Battlefield.

True to its name, the V2 Pro Ultralight feels almost weightless. Even compared with other lightweight gaming mice like the 2-ounce Logitech Pro X Superlight 2, the difference is palpable. The weight savings come from several sources: the mouse's modest frame, by offloading its wireless capability to a larger-than-average USB Type-C dongle, and by ditching traditional RGB lighting in favor of nothing more than a small LED as a low-battery indicator. This results in an unassuming mouse that moves effortlessly across virtually any surface.
Since it's so light, the Sabre V2 Pro Ultralight can take some getting used to. It wasn't distracting enough to ruin my experience, but using a peripheral that offered so little resistance forced me to be more measured in my movements.
Once the mouse and I were properly introduced, though, making smooth, rapid mouse movements was entirely effortless. While I love larger mice, I recognize how unwieldy they can be, and I can definitely appreciate a peripheral that feels more like a natural extension of your hand. I wouldn’t call the V2 Pro Ultralight ergonomic, but having a mouse this light makes it much easier to flex or pivot your wrist during repetitive motions.
To offer a little empirical evidence, I performed the same precision test with Aimlabs, a popular aim trainer, using the V2 Pro Ultralight. I pitted Corsair's mouse against my usual daily driver, the nearly 4-ounce Razer Basilisk V3 Pro. The test averages your accuracy and the number of targets hit in one minute. Following a brief warm-up, I found that the V2 Pro Ultralight consistently outperformed the Basilisk by a substantial margin.
Corsair’s Marksman S isn’t the most powerful sensor available, but 33,000dpi is more than sufficient to make your movements feel exceedingly precise. The 8,000Hz polling rate feels more responsive than the 1,000Hz polling rate in most gaming mice, but this has the unfortunate side effect of cutting into the V2 Pro Ultralight's battery life in a big way. The mouse can last up to 70 hours on a single charge, but only when operating at a 1,000Hz polling rate. Even with power-saving settings, I still got low-battery warnings several times a week.
It’s also worth noting that the Sabre V2 Pro Ultralight lacks Bluetooth connectivity, and the USB-C dongle requires a cable. This isn’t an issue on a desktop, but it becomes more awkward to manage on a laptop, where you may not want an extra cable dangling from your computer.
After years of tolerating cluttered software suites that will happily snack on your system’s RAM, makers like Corsair and Razer have started rolling out their own web-based configuration software. The Corsair Web Hub offers the bare essentials. You can set up to five different DPI settings, remap inputs, record macros, change the polling rate, and manage sleep settings. The Web Hub currently allows you to save up to four different profiles to the hardware, but it won’t automatically swap among them.
Currently, the software is only compatible with a handful of devices. And, curiously, the Sabre V2 Pro Ultralight isn’t compatible with iCue, Corsair’s desktop application. This doesn’t have a profound effect on how you can configure your mouse, but it might be a little inconvenient if you’re using this mouse with a collection of older Corsair peripherals.

Corsair’s lightest gaming mouse may not be its best, but the Sabre V2 Pro Ultralight offers excellent performance and a lightweight form factor that’s tough to beat. Logitech’s Pro X Superlight, long considered to be the gold standard for lightweight gaming mice, weighs more than twice as much and is significantly more expensive.
While you can certainly pay more for a mouse with a more powerful sensor or more enduring battery life, Corsair’s Sabre V2 Pro Ultralight is currently the best and lightest esports gaming mouse you can get for around $100.
