We’ve just reviewed the excellent Viper V2 Pro, one of the lighreview wireless gaming mice on the market at 58g, but it’s not the only model that Razer has chosen to renew and lighten. The manufacturer has also made modifications to its renowned DeathAdder to make it lighter, faster, and at the forefront of current technologies. So, here is our review of the Razer DeathAdder V3 Pro, a wireless, ultralight model, initially priced at €160, and available in both black and white.

This new DeathAdder maintains the essence of the series, but some aesthetic and practical modifications are worth noting. One can observe that the main buttons are less flared at the tip, the scroll wheel has been raised to better align with the index finger, and Razer’s logo is no longer backlit. These subtle changes result in a weight loss of approximately 25g — quite significant! — bringing the mouse down to 64g in the white version (and 63g for the black version). It can therefore be classified as an ultralight mouse, on par with models like the Logitech G Pro X Superlight or the Viper V2 Pro.

Razer DeathAdder V3 Pro Design Similarities with Viper

There are many similarities with the Viper in terms of design. The DeathAdder is entirely smooth plastic, which is not ideal for a good grip on the mouse. Just like with the Viper, the manufacturer has included non-slip adhesive panels to add to the sides and main buttons if needed, without significantly affecting the final weight. This improves the grip, preventing fingers from slipping during sudden movements. However, it’s worth noting that this mouse, as is often the case, is designed for right-handed users.

Ergonomic Comfort

While the Viper can be criticized for its relatively flat shape, making it less ergonomic, the Razer DeathAdder V3 Pro is much more comfortable in this regard. It has a more contoured and slightly beveled shape to fit the palm of the hand. The result is enhanced comfort, albeit with a few extra grams — particularly for players who use a palm grip — but of course, this is a matter of taste and preference.

Button and Scroll Wheel Performance

The main buttons have been replaced with Razer’s new 3rd-generation optical switches, ensuring swift execution and high precision. Their lifespan is guaranteed for 90 million clicks. While the secondary buttons don’t benefit from the same treatment, they are surprisingly responsive and firmly anchored to the shell. Additionally, there is another button on the scroll wheel and one beneath the mouse, and nothing more.

The scroll wheel, on the other hand, is quite basic: its notches are well-defined, and the mouse doesn’t offer smooth or free-scrolling. It is primarily designed for gaming and may not be as effective for office work. While this isn’t its primary use, other models like the Basilisk V3 are more versatile (albeit heavier, it should be noted).

Power and Connectivity

A “power” button located under the mouse allows for switching it off. It also serves as a sensitivity adjustment to increase the levels (of which there are five), although it must be admitted that this position isn’t very practical if you want to change sensitivity mid-game.

The PTFE feet positioned all around ensure smooth gliding on the mouse pad. As for connectivity, Bluetooth is no longer available. While it can be useful for office use or when you want to use your mouse on another computer while on the go, it is obviously not recommended for gaming, and its absence doesn’t seem bothersome. The Hyperspeed 2.4 GHz receiver offers minimal latency, much more suitable for gaming.

Razer provides a braided USB-C charging cable with an adapter for the receiver; in case of battery depletion, you can switch from wireless to wired connection in just a few seconds. According to the manufacturer, the battery life has increased from 70 hours in the previous version to 90 hours, allowing for a substantial amount of gameplay before needing to recharge.

Razer DeathAdder V3 Pro Precision

As with the Viper V2 Pro, Razer has opted for its new optical sensor, the Focus Pro 30K, derived from the Pixart sensor. It is even more precise than its previous Focus+ sensor and consumes less power. We don’t really need to question its performance. With adjustable sensitivity of up to 30,000 dpi and maximum accelerations of 70g, the Focus Pro 30K is one of the best sensors currently available, even though these exceptional numbers don’t have much impact in actual gameplay. Additionally, it is now possible to use it on a glass desk, which can be handy on occasion. Lastly, the polling rate is 1000 Hz, a now-standard value in gaming mice.

Razer DeathAdder V3 Pro of Conclusion

The Razer DeathAdder V3 Pro successfully embraces the direction of ultra-lightweight wireless design (64g) and proves to be more ergonomic than the V2 Pro. Its excellent Focus Pro 30K sensor and precise, swift optical switches make it a mouse perfectly suited for FPS gaming. On the flip side, the lack of buttons and the notched scroll wheel limit its suitability for certain games and software (such as MOBAs, MMOs, or office applications). This is a factor to consider when making your decision.
