Corsair Saber V2 Pro Ultralight Wireless Review: A Lightweight Mouse That Beats Its Price

Introduction

It has been a long time since Corsair was a serious contender in the gaming mouse space. The last model that earned any extended desk time was the M65 RGB Pro from 2016. Since then, the brand has often felt a step behind the rest of the industry. The Saber V2 Pro Ultralight Wireless aims to change that. After spending a lot of time with it, this mouse deserves a closer look.

At a glance, it ticks most of the boxes expected from a modern performance mouse. It is a small to medium size, supports 8K polling, offers a decent 70-hour battery life at 1,000 Hz, and uses a web-based configurator. The advertised weight is 36 grams, and on the scale it actually beats that figure, feet included. The shell is solid on both top and bottom. And at around $100, it is a refreshing price compared to what the top end of the market has been charging.

Who This Mouse Is For

The Saber V2 Pro Ultralight Wireless is aimed at competitive players who want the lightest possible mouse without paying flagship prices. Its sub-36 gram weight puts it at the lowest end of what is currently available, which makes it especially appealing for fast, flick-heavy aiming in shooters.

The small to medium size and low front height make it a natural fit for fingertip grip users. With a hand measurement of 20.5 x 10.5 cm, it is almost exclusively a fingertip grip mouse. Those with smaller hands will likely find it comfortable for claw grip as well. The shape has a central hump that sits at 38 mm high, which is taller than expected for a mouse this size, and the sides angle inward fairly aggressively toward the bottom plate.

The rear flare is not exaggerated, but it provides just enough room to anchor the pinky. This makes the grip repeatable and consistent during long sessions. If you are looking for a lightweight mouse that disappears in your hand, this is a strong candidate.

Shape and Build Quality

The dimensions come in at roughly 119 mm long, 63 mm wide, and 38 mm high. The length places it very close to the size one Pulsar stove, while the height puts it in the same territory as the ULX medium or the Pulsar X2 size 2. It feels a touch narrower than the X2H or the Viper V3 Pro because of the aggressive inward angle of the sides.

First impressions of the build lean toward the cheap side, and that is almost entirely due to the combination of the extreme lightweight and the texture of the plastic. The material feels soft rather than rigid, which is hard to describe without holding it. The lack of a coating can also make it feel slippery, especially for those with sweaty palms. The included grips are the way to go here.

From a sidewall standpoint, the shell is solid. Getting any flex requires intentionally squeezing in a way that would never happen during normal play. There has been some attention drawn to the top shell having give when pushing a thumb directly into it. That is not a realistic use case. The shell strength is more than adequate for using this as a gaming mouse. Achieving a sub-36 gram weight with a solid top shell and bottom plate is commendable.

The switches are Corsair’s custom-tuned tactile mechanical switches. The main triggers are decent but not the crispest available. There is a minimal but noticeable amount of pre and post travel on the triggers. They are light and easy to spam, but they would not be the first choice for those who prefer a very crisp click.

The side buttons are where the mouse falls short. There is no pre-travel and the switches themselves feel good, but there is post travel and a noticeable margin between the front and rear buttons. The rear button feels like it keeps going into the shell, as if the entire bracing assembly moves after the button bottoms out. This is the clearest area of opportunity for the mouse.

The scroll wheel, on the other hand, feels excellent. It has a solid build, a medium notch tactility, and is quiet. The click is light enough to spam but not so light that it triggers accidentally.

Sensor and Wireless Performance

The sensor is called the Corsair Marksman S and is rated up to 33,000 DPI. One detail that stands out immediately is that the sensor is not centered on the body. It sits about 60% toward the rear, which seems odd on paper. In practice, it made no difference at all. There was no learning curve or adjustment period, and everything felt natural in game.

The mouse feels very solid in wireless use. There were no sensor issues and no wireless issues during testing. Running at 8K polling for a good portion of the testing produced no performance problems, but it does eat battery life. At 8K, the rated battery life drops to around 16 hours. The 2,000 Hz polling rate remains the sweet spot for balancing performance gains with battery life. Running at 1,000 Hz gets up to 70 hours.

There is no Bluetooth support here, which is a feature found on some competing models. The feature set is also thinner compared to flagships from Logitech and Razer. Missing features include liftoff distance adjustment, sensor matching, rotational correction, and auto polling rate adjustment. Most of the time, those features require always-on software running in the background, whereas this mouse uses a lightweight web configurator.

Software and Configurator

The Saber V2 Pro Ultralight Wireless does not currently use Corsair’s iCUE software. Instead, it uses the web-based configurator called WebHub, which first rolled out with the Maker 75 keyboard. It is good to see Corsair continuing to expand this approach to other peripherals.

The configurator is fairly spartan for now. It includes key remapping, a macro manager, and a settings menu for firmware and polling rate selection. DPI settings are available, with support for up to five presets or as few as one. Unlike some flagship mice, DPI steps are limited to increments of 50. There is no physical DPI button, but a long press of the right trigger and back button for three seconds cycles through the selected DPI presets.

There is currently no support for this mouse in iCUE, though Corsair has announced that support will be added in the future. No date has been set yet. If WebHub continues to be fleshed out, or if the upcoming iCUE support adds more features, it could close the feature gap with competitors fairly easily.

Buying Advice

At $100, the Saber V2 Pro Ultralight Wireless is more affordable than most mice in its performance class by a wide margin. The weight is at the lowest end of what is available, and the price even beats offerings from Pulsar and WL Mouse. The build feel would raise eyebrows at the $150 mark, but at $100 with this weight, this performance, the included accessories, and the web configurator, it is an impressive package.

The box includes the dongle with a mouse pad clip, the cable, a full set of grips, and alternate large glides with an extra glide for the sensor. The included glides are not super fast, but there is plenty of room underneath if you prefer to use dot skates, which work well for fingertip grip on a control pad.

The main downsides are the side button assembly, the slippery coating, and the thin feature set compared to flagship models. If Corsair addresses the side buttons and continues to develop the software, this mouse could become a serious contender in the peripheral space.

Conclusion

The Corsair Saber V2 Pro Ultralight Wireless is a strong return to form for Corsair. It delivers an exceptional weight, solid wireless performance, and a price that undercuts most of the competition. The shape is well executed, the scroll wheel is excellent, and the web configurator is a welcome change from heavy always-on software.

The side buttons need work, and the feature set is thinner than what Logitech and Razer offer at the top end. But at $100, with this weight and performance, it is easy to recommend. Corsair is headed in the right direction, and if they keep this up, they will definitely be back in the conversation for peripherals.
