# They fixed it! But at what cost? - Corsair Sabre V2 Pro Source: https://www.youtube.com/watch?v=ghawYhsGdug Recap page: https://rapidrecap.app/video/ghawYhsGdug Generated: 2026-01-15T22:34:59.599+00:00 --- ## Quick Overview The Corsair Sabre V2 Pro, while lightweight and featuring a high-end Marksman S sensor and 8000Hz polling rate, suffers from a significant input latency issue (9ms wireless, 8.2ms wired) caused by double-clicking/debouncing, which the reviewer considers a major flaw that outweighs its excellent specs and low weight for competitive gaming. **Key Points:** - The Corsair Sabre V2 Pro weighs an extremely light 36g (0.08 lb) without using a honeycomb design. - The mouse features the high-performance Corsair Marksman S sensor, supporting up to 33,000 DPI, 750 IPS tracking speed, and 50G acceleration. - It supports an 8000Hz polling rate, offering 16 hours of battery life at that setting, or 70 hours at the standard 1000Hz. - Wired click latency measured 8.2 ms, while wireless (8000Hz) measured 8.4 ms, which the reviewer deems too high compared to the 1ms gold standard. - The primary issue stems from double-clicking/smash-clicking debouncing, which adds noticeable input latency (9ms wireless, 8.2ms wired). - The mouse includes accessories like extra grip tape (3M adhesive), an alcohol pad, and PTFE glides. - The reviewer suggests this latency issue is a major drawback, especially given the $99.99 price point, making it less recommendable than cheaper competitors like the Dareu A950 Wing. ![Screenshot at 0:09: The reviewer unboxes the Corsair Sabre V2 Pro Ultralight Wireless mouse, immediately highlighting the product's packaging and first look.](https://ss.rapidrecap.app/screens/ghawYhsGdug/00-00-09.jpg) **Context:** This video is a review of the Corsair Sabre V2 Pro Ultralight Wireless gaming mouse, focusing heavily on its performance metrics, especially latency, compared to industry standards and competitors. The reviewer unboxes the product, discusses its physical features and included accessories, and then dives into objective testing results from TechPowerUp regarding click latency before testing its responsiveness in the game Apex Legends. ## Detailed Analysis The Corsair Sabre V2 Pro is an ultralight wireless gaming mouse weighing only 36g, achieved without a honeycomb shell. It utilizes the Corsair Marksman S sensor, capable of 33,000 DPI, 750 IPS, and 50G acceleration. The mouse supports an 8000Hz polling rate, yielding 16 hours of battery life at that setting or 70 hours at 1000Hz. Upon testing click latency, the wired mode measured 8.2 ms, and wireless at 8000Hz measured 8.4 ms, both significantly above the sub-1ms standard for top-tier gaming mice. The reviewer attributes this latency issue to the mouse's debouncing settings designed to prevent double-clicking, which adds 8-9ms of delay. While the mouse feels great physically—lightweight and featuring good main button clicks—the reviewer finds the fixed, high latency a significant drawback, especially considering its $99.99 price, suggesting competitors like the Dareu A950 Wing offer similar specs for less money without this latency penalty. The reviewer notes that while Corsair offers firmware updates, the latency issue appears inherent to the current switch tuning. ### Unboxing and Features - Corsair Sabre V2 Pro Ultralight Wireless - Mouse weighs 36g (0.08 lb) without honeycomb design - Includes a Slipstream 8K Wireless Receiver (USB-C), 6ft USB-A to C cable, grip tape, alcohol pad, and extra-smooth glides. ### Performance Specs - Features the Corsair Marksman S Sensor (100-33,000 DPI, 750 IPS, 50G acceleration) - Supports up to 8000Hz Polling Rate - Battery life is 70h at 1000Hz or 16h at 8000Hz. ### Latency Testing Results - Wired click latency measured 8.2 ms (standard deviation 0.06 ms) - Wireless latency at 8000Hz measured 8.4 ms (standard deviation 0.09 ms) - This is considered a significant flaw compared to the sub-1ms standard. ### Physical Impressions - Main buttons use Corsair Mechanical Switches rated for 100 million clicks - Clicks feel medium travel, not too loud, but the side buttons feel mushy - The overall lightweight build feels excellent and responsive in-game. ### Software and Customization - Configuration requires the CORSAIR WEB HUB (no dedicated IQ software needed) - Software allows adjustment of DPI stages, polling rate (125Hz up to 8000Hz), sleep time, and button mapping/macros. ### Conclusion and Value - At $99.99, the high latency is a major disadvantage, especially since competitors offer similar ultra-light mice cheaper without this input lag. The reviewer suggests waiting for a firmware fix to address the debouncing latency. ![Screenshot at 0:09: Reviewer showing the Corsair Sabre V2 Pro packaging during the unboxing segment.](https://ss.rapidrecap.app/screens/ghawYhsGdug/00-00-09.jpg) ![Screenshot at 0:27: Close-up on the unboxed accessories, including the Slipstream 8K Wireless Receiver and the USB-A to C cable.](https://ss.rapidrecap.app/screens/ghawYhsGdug/00-00-27.jpg) ![Screenshot at 1:18: On-screen graphic displaying the weight of the mouse: 0.08 lb \(36g\).](https://ss.rapidrecap.app/screens/ghawYhsGdug/00-01-18.jpg) ![Screenshot at 1:44: On-screen graphic detailing the Corsair Marksman S Sensor specifications: 100-33,000 DPI, 750 IPS, 50G Max Acceleration.](https://ss.rapidrecap.app/screens/ghawYhsGdug/00-01-44.jpg) ![Screenshot at 6:52: TechPowerUp latency results showing the Sabre V2 Pro wireless latency at 8000Hz measured at 8.4 ms.](https://ss.rapidrecap.app/screens/ghawYhsGdug/00-06-52.jpg)
