Corsair launched the Sabre v3 Pro PureVector series on 20 October 2026. The lightest model weighs 37 grams, but the weight is not the main story. These mice can use a different sensitivity depending on which direction you move.
The feature is called PureVector. Corsair built it with Aimlabs, the aim training company, and it only works on these six mice.
What PureVector Actually Does
Most people aim better in some directions than others. PureVector tries to measure that.
You run a calibration sequence in Aimlabs, which records how you move in each direction. The system then adjusts your sensitivity by direction, aiming to offset weak spots. Corsair says the finished profile is saved to the mouse firmware, so it works in any game with no background app running.
Going by Corsair’s description, this changes how the mouse responds to your hand. Nothing in the release says it detects targets or moves your crosshair for you, so it is not aim assist in the usual sense.

Corsair’s release does not list prices. These come from a report on the announcement, which gives one price per family, so check the current listing before you buy.
All six use Corsair’s Marksman X sensor, rated at 42,000 DPI, with polling up to 8,000Hz wired or wireless. Corsair notes that reaching 8,000Hz depends on your CPU.
Battery life on the Ultralight models is rated at up to 140 hours at 1,000Hz, or 25 hours at 8,000Hz. The MG and CF models are rated at up to 200 hours and 31 hours.
Why the 81ms Claim Needs Checking
Corsair says testing showed up to an 81ms, or 33 percent, reduction in the aiming and correction part of a shot.
Treat that as a best case. The words “up to” matter, and the release does not give the test method, the number of players or what the mice were compared against. We found no independent test confirming the figure.
We have not tested these mice ourselves.
What Early Reviews Say
KitGuru liked that the profile lives on the mouse, but criticised mushy clicks on the CF model and its high price. It suggested the cheaper plastic version may be the better buy.
Polish site Antyweb was positive about the Ultralight, saying it improves nearly everything that could be criticised in the previous model.
Is It Allowed in Competition?
Corsair’s release does not mention tournament rules or anti-cheat software. If you play in an organised league, ask the organiser before relying on it.
Should You Buy One?
Worth a look if: you already want a premium lightweight mouse and you are curious about aim training.
Wait if: you want proof first. There is still no public test method behind the headline number, and a change in sensitivity will not replace practice.
