The Attac Shark X3 mouse has good build quality and the sensor is quite precise ( Tested on Valorant, CS:GO 2, and Rivals), with zero noticeable input lag.
Battery life is excellent, lasting 1.5 weeks on 2.5 GHz and around 1 week using Bluetooth.
The primary buttons are initially a bit stiff, but they don't cause significant issues.
While the UI could be improved, it still gets the job done.
The charging speed is fast, and the included braided cable is both durable and light, even when used in wired mode.
