Corsair Sabre v2 Pro Ultralight

Manufacturer: Corsair

The Corsair Sabre v2 Pro Ultralight is a right-handed gaming mouse built around a notably lightweight 36 g frame, making it a practical choice for users who prioritize reduced hand fatigue during extended sessions. It connects via 2.4 GHz wireless or USB, includes Bluetooth 4.2 support, and is powered by a rechargeable battery rated for up to 70 hours of use. The mouse can also be used while charging, adding flexibility to its wireless setup.

At its core, the Sabre v2 Pro Ultralight uses the Corsair Marksman S sensor, which supports a DPI range of 100 to 33000, adjustable to suit different use cases. The polling rate reaches 8000 Hz, with a maximum tracked speed of 750 IPS and 50G acceleration. It features 5 programmable buttons, including 2 side buttons and a DPI switching button, along with RGB lighting and one onboard memory profile. Physical dimensions come in at 119 mm in height, 63 mm in width, and 38 mm in thickness, with a 1.8 m cable included.

Pros
  • At 36 g, the mouse is very light, which reduces strain during long use sessions
  • The polling rate of 8000 Hz allows for highly responsive cursor tracking
  • DPI is adjustable between 100 and 33000, covering a wide range of sensitivity preferences
  • A 70-hour battery life means infrequent recharging is needed during regular use
  • The mouse can be used while charging, so a low battery does not interrupt usage
  • All 5 buttons are programmable, offering flexibility in how inputs are configured
Cons
  • Only one onboard memory profile is available, limiting how many configurations can be stored on the device
  • The mouse is exclusively right-handed, making it unsuitable for left-handed users
  • Wireless charging is not supported, requiring a physical cable to recharge
  • There is no profile switching button, so changing profiles on the fly is not possible directly from the mouse
  • The scroll wheel does not tilt and there is no thumb scroll wheel, reducing navigation options
Who is this for?

This mouse is well suited to right-handed users who prioritize low-weight peripherals for extended gaming or productivity sessions, as the 36 g build reduces physical fatigue over time. The 8000 Hz polling rate and 33000 DPI ceiling make it a strong fit for users who demand precise, fast cursor tracking — particularly in fast-paced gaming scenarios where responsiveness matters. The 70-hour battery life combined with the ability to use the mouse while charging also makes it a practical option for users who need reliable wireless operation without frequent interruptions.

Who is this NOT for?

Users who require ambidextrous or left-handed ergonomics will find this mouse unsuitable, as it is designed exclusively for right-handed use. Those who rely on multiple onboard profiles for switching between different configurations on the fly will be limited by the single onboard memory slot and the absence of a profile switching button. Additionally, users who prefer expanded scroll navigation — such as those doing horizontal scrolling or using a thumb scroll wheel for media or productivity tasks — will find the scroll wheel options lacking, as neither tilting nor thumb scroll functionality is available.

Final Verdict

The Corsair Sabre v2 Pro Ultralight is a right-handed gaming mouse built around a clear set of priorities: minimal weight, high-frequency tracking, and dependable wireless performance. Its 36 g frame paired with an 8000 Hz polling rate makes it a well-suited option for users who demand responsive, low-fatigue input over extended sessions, while the 70-hour battery life adds practical day-to-day reliability. The trade-offs — a single onboard profile, no profile switching button, and right-handed-only ergonomics — mean it serves a specific rather than universal audience. For right-handed users whose needs align with its design focus, the Sabre v2 Pro Ultralight delivers a technically capable and well-rounded package within its intended scope.
