The Razer DeathAdder V4 Pro is a lightweight wireless gaming mouse that continues Razer's longstanding DeathAdder lineup. It has the same right-handed ergonomic shape as the previous generation Razer DeathAdder V3 Pro, making it best suited for larger hands. The updates are mostly internal: It features a new MCU model, an updated sensor, optical switches for the main clicks, and an optical scroll wheel encoder designed to provide better long-term reliability than the mechanical encoders of past models. It's also slightly lighter than its predecessor. Finally, it ships with Razer's second-generation wireless dongle, which supports polling rates up to 8000Hz. Razer advertises this new dongle version as more stable with better signal strength, while also promising improved battery life.
Our Verdict
The Razer DeathAdder V4 Pro isn't designed for work. Despite this, it's still decently well-suited for it. It has a comfortable right-handed shape, though it's best suited for larger-sized hands. It also has excellent build quality. That said, it lacks productivity features like Bluetooth support for multi-device pairing, a scroll wheel with left-right tilt functions, and a free-scrolling mode.
Excellent build quality.
Scroll wheel lacks left-right inputs and a free-scrolling mode.
No Bluetooth support for multi-device pairing.
Only suitable for larger-sized hands.
The Razer DeathAdder V4 Pro is outstanding for playing FPS games. It's very lightweight for its size, making it easy to move around quickly and accurately. Its right-handed ergo shape is best-suited for a palm grip for larger-sized hands. Performance-wise, it supports a wired or wireless polling rate of 8000Hz and offers exceptionally low click and sensor latency, ideally suited for competitive play. That said, while the overall build quality is excellent, it suffers from some minor creaking if you tend to squeeze quite forcefully while gaming.
Exceptionally good sensor performance.
Outstanding click latency.
Impressively lightweight.
Excellent build quality.
Only suitable for larger-sized hands.
The DeathAdder V4 Pro is great for MMO and MOBA gaming. Build quality is excellent aside from minor flexibility and faint creaking if you press very hard on the shell. Its comfortable right-handed ergo shape and strong overall performance make it a reliable choice. However, its biggest drawback is the limited number of side buttons compared to dedicated MMO mice. You can work around this by relying more heavily on keyboard input or remapping buttons, creating macros, or even setting a Hypershift button to toggle a secondary input layer in the software.
Exceptionally good sensor performance.
Outstanding click latency.
Excellent build quality.
Only suitable for larger-sized hands.
Fewer additional buttons than dedicated MMO mice.
The DeathAdder V4 Pro has exceptionally good raw performance. It offers extremely low and consistent click latency and outstanding overall sensor performance, making it ideal for competitive gaming in any genre. It also supports a maximum polling rate of 8000Hz both in wired and wireless modes, which is noteworthy as many wireless 8k-capable mice only support 8k wireless.
Exceptionally good sensor performance.
Outstanding click latency.
Maximum wired and wireless polling rate of 8000Hz.

Popular Mouse Comparisons
The Razer DeathAdder V4 Pro continues Razer's longstanding DeathAdder line of right-handed ergonomic gaming mice. It keeps the small shape revisions introduced with the Razer DeathAdder V3 Pro but makes several incremental changes under the hood, including a new generation sensor, updated optical switches, a slightly lighter weight, a longer advertised battery life, and Razer's second-generation HyperPolling dongle with support for up to 8000Hz polling.
One of the most meaningful hardware changes is the adoption of an optical scroll wheel encoder and a full-size switch for the middle click. Previous DeathAdder models (and most mice in the industry) use smaller side-button-style switches for the mouse wheel click, which are typically less durable. We also expect the new optical encoder to be more durable than the mechanical encoders still used by most competitors. Since scroll wheels are a well-documented failure point in gaming mice, this change targets one of the most significant weaknesses in long-term reliability.
The DeathAdder V4 Pro is currently the leading 'ergo' option for competitive play. However, while the changes it makes from the DeathAdder V3 Pro are all improvements, they're iterative. Aside from its improved battery life and potentially more reliable scroll wheel, any measurable performance gains over much cheaper options simply aren't noticeable in-game. Budget models such as the MCHOSE L7 Ultra, upper mid-range models like the LAMZU THORN, and even established premium flagships, like the last-gen Razer DeathAdder V3 Pro, the Razer Viper V3 Pro, and the Logitech G PRO X SUPERLIGHT 2 DEX, deliver very similar performance at a lower cost.

The Razer Viper V3 Pro and the Razer DeathAdder V4 Pro are lightweight wireless gaming mice designed for high-level competitive play. They use virtually the same internal components and deliver similarly outstanding raw performance. The main difference is shape: the Viper has a low-profile symmetrical shape with a moderate hump in the middle, making it a versatile option for most hand sizes and grip types. In contrast, the DeathAdder has a larger, more curvaceous right-handed shape with a taller, more pronounced hump, making it a better fit for larger hands using a palm grip.
The Logitech G PRO X SUPERLIGHT 2 and the Razer DeathAdder V4 Pro are very lightweight wireless gaming mice with comparable performance. Where they differ most is shape: The Logitech is widely seen as a very accommodating shape for most hand sizes and grip types. Comparatively, the Razer has a slightly larger, exclusively right-handed shape best suited for medium or larger-sized hands using a palm grip.
The Razer DeathAdder V4 Pro and the Razer DeathAdder V3 Pro are lightweight wireless gaming mice designed for competitive play. They share the same right-handed ergo shape, but the V4 Pro is lighter and offers a better-advertised battery life, an updated sensor, and an optical scroll wheel encoder that should improve long-term durability. The V4 Pro also includes an 8k-capable dongle in the box, while the V3 Pro supports 8k polling only with a separate purchase. Both feel comfortable for larger hands using a palm grip, but the V4 Pro's slightly wider side button spacing makes them easier to distinguish by feel. It also adds extra software features like Dynamic Sensitivity and Sensor Rotation, which the V3 lacks.
The Razer DeathAdder V4 Pro and the Logitech G PRO X SUPERLIGHT 2 DEX are both premium wireless gaming mice built for competitive play. They're about the same weight and share a right-handed ergo shape, but the Logitech feels more accommodating to a wider range of hand sizes and grip styles. Both deliver excellent performance and include 8k-capable wireless dongles. The Razer stands out with smoother-gliding feet and an optical scroll wheel encoder that should improve long-term durability compared to the Logitech's mechanical wheel. It also offers unique software features like Dynamic Sensitivity and a Sensor Rotation tool, which the Logitech lacks.
