Review: Razer DeathAdder V4 Pro features pro input from NiKo, Spinx, and more

Razer recently launched the DeathAdder V4 Pro, which is a new version of its flagship gaming mouse shaped by feedback from top esports players like Nikola "NiKo" Kovač and Lotan "Spinx" Giladi. The mouse introduces several upgrades, including a new optical scroll wheel and improved internals. It also features HyperPolling Wireless technology with up to 8,000 Hz polling for both wired and wireless play. Here’s a closer look at the Razer DeathAdder V4 Pro and why it’s touted as the mouse for champions.

One of the most unique aspects of the Razer DeathAdder V4 Pro is that it was built using direct input from top esports players such as NiKo and Spinx. According to Razer, both players tested early prototypes and gave feedback on everything from button placement to texture.

By distributing units to pro players for live feedback during esports events, the Razer team developed a final design that retains the line's ergonomic shape. In addition to NiKo and Spinx, the majority of participating pros also insisted on keeping that shape unchanged.

After testing the Razer DeathAdder V4 Pro, we found that it felt comfortable even during long sessions of Overwatch 2 and Marvel Rivals. Its ergonomic shape helped prevent wrist strain and the light weight of 56g added to a better experience in terms of ergonomics. A nice bonus is that the mouse is made with a bio-based polymer and recycled materials for sustainability purposes.

In terms of responsiveness, it stayed consistent throughout each match. Every click registered smoothly both at 1000 Hz and 8000 Hz. We didn't experience any accidental double clicks at all, and the tracking felt very precise when we aimed for headshots as Widowmaker, for example.

We used the mouse for an entire weekend without needing to charge it, and the dongle lit up with three indicators for battery life, connection status, and polling rate. While we tested the mouse at our office, players who wish to bring their own gear to LANs or other events can count on it to remain reliable in terms of battery life. For even longer battery life, we'd recommend the 1000 Hz polling rate.

Customizing the Razer DeathAdder V4 Pro was easy, too. We matched our old mouse sensitivity, adjusted DPI in precise increments, and chose from three curve profiles. These profiles could also be customized based on hand speed.

If you'd like to get the lowdown, then below are the specifications for the Razer DeathAdder V4 Pro as well.

All in all, this is a great mouse to bring into your setup if you want something designed for serious gameplay. It costs $249.99 CAD, which is about $169.99 USD.
