What reviewers say

The RTINGS.com review describes the Razer DeathAdder V4 Pro as a lightweight wireless gaming mouse that builds on the previous V3 Pro with internal upgrades such as a new MCU, updated sensor, optical switches for clicks, an optical scroll‑wheel encoder, and a second‑generation HyperPolling dongle supporting up to 8000 Hz. The reviewer notes its right‑handed ergonomic shape is best suited for larger hands, praises the excellent build quality, and highlights very low click and sensor latency suitable for competitive play. Drawbacks include lack of Bluetooth multi‑device pairing, no left‑right tilt or free‑scrolling mode on the wheel, and limited side buttons compared to MMO‑focused mice.

The Verge review notes that the new DeathAdder V4 Pro is a lighter, faster version of its predecessor with upgraded optical sensors—including an optical scroll wheel—and supports up to 8,000 Hz polling in both wired and wireless modes. It highlights the improved precision and durability of the new components while pointing out design drawbacks such as its asymmetrical shape for right‑handed users and an oversized form factor that may only suit larger hands.

WIRED’s review praises the Razer DeathAdder V4 Pro for its lightweight 56‑gram build, high‑end optical sensor (45,000 dpi), snappy buttons, responsive wheel, and ergonomic shape that feels agile yet comfortable. The reviewer highlights the practical USB‑C dongle with useful LED indicators and notes the mouse’s excellent performance at both 1,000‑Hz and 8,000‑Hz polling rates. Downsides mentioned include limited battery life at maximum polling, occasional random low‑battery alerts, and a tendency for oils to build up on the matte plastic surface.

TechRadar praises the Razer DeathAdder V4 Pro as a flawless evolution of its predecessor, highlighting improved ergonomics, ultra‑fast performance, an optical scroll wheel, and extended battery life. The review notes the lack of RGB lighting and higher price as minor drawbacks but overall recommends it for serious gamers seeking top‑tier functionality.

Windows Central’s review praises the Razer DeathAdder V4 Pro for its exceptional performance, noting it as one of the highest‑performance gaming mice available. The article highlights major internal upgrades—new sensor, switches, scroll wheel, and especially the HyperSpeed Wireless Gen‑2 dongle—while acknowledging that the exterior design remains largely unchanged. It commends the light weight (56–57 g), long battery life (up to 150 hours at 1 000 Hz polling rate), and overall smoothness, but cautions that the high price is justified only for users who prioritize performance.

Tom’s Hardware reviews the Razer DeathAdder V4 Pro as a solid upgrade to its predecessor, praising its excellent shape, lightweight design, and inclusion of an 8K wireless dongle. The review notes that while it offers a newer sensor, optical switches, and better battery life, the price ($170) and marginal performance gains over the V3 Pro may not justify an upgrade for everyone.

PCMag Middle East’s review praises the Razer DeathAdder V4 Pro as a top‑tier esports mouse, highlighting its lightweight design, ultra‑high‑resolution Focus Pro 45K sensor, upgraded Gen‑4 optical switches, and improved wireless dongle that delivers low latency. The reviewer notes it earns their Editors’ Choice award for the category and calls it "one of the best esports mice Razer has released."

The Razer DeathAdder V4 Pro retains its classic ergonomic shape and feels lightweight at 56 g while offering wireless performance that the reviewer finds indistinguishable from wired. The heavy receiver puck stays put, grip tape is included, and battery life is ample. However, Synapse software remains problematic—no Web support for this model—and the USB‑A to USB‑C cable can be inconvenient on USB‑C‑only laptops. Overall, it’s recommended for users upgrading from older mice who value comfort and performance, though the price may be a consideration.

Our take

Based on 8 reviews

All eight reviews agree the Razer DeathAdder V4 Pro delivers top-tier performance with its lightweight 56-gram design, Focus Pro 45K sensor, and 8K wireless polling. Reviewers consistently praise its ergonomic shape for larger hands, snappy optical switches, and excellent build quality. Based on their tests, we conclude it is a highly capable esports mouse that justifies its premium positioning for competitive players.

However, reviewers split on whether its marginal upgrades over the V3 Pro justify the price. RTINGS and The Verge note its asymmetrical shape limits it to larger hands, while WIRED and PCMag highlight its comfort. Buyers should weigh the high cost against the need for these specific internal upgrades rather than expecting a completely new experience.
