Razer DeathAdder V4
After 5 weeks of daily FPS play, aim training, and general desktop use, the Razer DeathAdder V4 is the best ergonomic shape Razer has ever made. The V4 takes the proven V3 silhouette and pairs it with the new Focus Pro 45K sensor, an 8000Hz wireless polling rate, and a battery that lasts almost twice as long. At $109 it is priced aggressively against the Logitech Superlight 2 while keeping the right-handed ergonomic shape Razer fans expect.

How This Was Tested
The DeathAdder V4 was tested over 5 weeks across CS2, Valorant, Apex Legends, and Aim Lab. Click latency was measured with a high-speed camera, polling rate verified with MouseTester, and battery life logged across multiple full charge cycles at 1000Hz and 8000Hz. Comparisons drawn from time spent with the V3 Pro and Logitech Pro X Superlight 2.
Frequently Asked Questions
For most V3 Pro owners, no. The shape is the same, click feel is similar, and the V3 Pro sensor is still excellent. The upgrade is meaningful if you specifically want native 8000Hz polling (the V3 Pro needed a separate dongle), longer battery life, or the lighter 56g weight. Otherwise the V3 Pro remains a great mouse for years to come.
They target different hand sizes and grip styles. The Superlight 2 is symmetrical and ambidextrous, ideal for fingertip and claw grip with medium hands. The DeathAdder V4 is right-handed ergonomic, ideal for palm grip with medium-to-large hands. The V4 is $50 cheaper, has 8000Hz native polling, and longer battery life. The Superlight 2 has the more proven competitive pedigree but the V4 specs match or beat it.
For most players, no. The visible difference between 1000Hz and 8000Hz polling is negligible unless you have a 240Hz+ monitor and CPU headroom to spare. 8000Hz also halves the battery life. Run 1000Hz for daily use and only enable 8000Hz for ranked competitive sessions if you have the hardware to benefit.
