Razer DeathAdder V4 Pro

The DeathAdder V4 Pro trims Razer's ergonomic esports mouse to 56 g and upgrades it with a Focus Pro 45K Gen-2 sensor, Gen-4 optical switches rated for 100 million clicks and 8,000 Hz polling in both wireless and wired modes, with the 8 kHz dongle in the box. Battery life is rated up to 150 hours at 1,000 Hz but 22 hours at 8,000 Hz. Tom's Hardware and PC Gamer rate it highly, though both suggest the older V3 Pro covers most players' needs.
